Unfortunately he didn't find the overall score of the match; however, he got hold of a profound description of the match's process. On the whole there are n lines in that description each of which described one goal. Every goal was marked with the name of the team that had scored it. Help Vasya, learn the name of the team that won the finals. It is guaranteed that the match did not end in a tie.\n\nInput\nThe first line contains an integer n (1 ≤ n ≤ 100) — the number of lines in the description. Then follow n lines — for each goal the names of the teams that scored it. The names are non-empty lines consisting of uppercase Latin letters whose lengths do not exceed 10 symbols. It is guaranteed that the match did not end in a tie and the description contains no more than two different teams.\n\nOutput\nPrint the name of the winning team.

On the whole there are n lines in that description each of which described one goal. Every goal was marked with the name of the team that had scored it.

It is guaranteed that the match did not end in a tie and the description contains no more than two different teams.\r\n\r\nOutput\r\nPrint the name of the winning team.

Unfortunately he didn't find the overall score of the match; however, he got hold of a profound description of the match's process. On the whole there are n lines in that description each of which described one goal. Every goal was marked with the name of the team that had scored it. Help Vasya, learn the name of the team that won the finals. It is guaranteed that the match did not end in a tie.\nInput\n\nThe first line contains an integer n (1 ≤ n ≤ 100) — the number of lines in the description. Then follow n lines — for each goal the names of the teams that scored it. The names are non-empty lines consisting of uppercase Latin letters whose lengths do not exceed 10 symbols. It is guaranteed that the match did not end in a tie and the description contains no more than two different teams.\nOutput\n\nPrint the name of the winning team.

was an extremely gifted student. He was great at everything including Combinatorics, Algebra, Number Theory, Geometry, Calculus, etc. He was not only smart but extraordinarily fast! He could manage to sum 1018 numbers in a single second.\n\nOne day in 230 AD Shapur was trying to find out if any one can possibly do calculations faster than him. As a result he made a very great contest and asked every one to come and take part.\n\nIn his contest he gave the contestants many different pairs of numbers. Each number is made from digits 0 or 1. The contestants should write a new number corresponding to the given pair of numbers. The rule is simple: The i-th digit of the answer is 1 if and only if the i-th digit of the two given numbers differ. In the other case the i-th digit of the answer is 0.\n\nShapur made many numbers and first tried his own speed. He saw that he can perform these operations on numbers of length ∞ (length of a number is number of digits in it) in a glance! He always gives correct answers so he expects the contestants to give correct answers, too. He is a good fellow so he won't give anyone very big numbers and he always gives one person numbers of same length.\n\nNow you are going to take part in Shapur's contest. See if you are faster and more accurate.\n\nInput\nThere are two lines in each input. Each of them contains a single number. It is guaranteed that the numbers are made from 0 and 1 only and that their length is same. The numbers may start with 0. The length of each number doesn't exceed 100.\n\nOutput\nWrite one line — the corresponding answer. Do not omit the leading 0s.\n\n\"\"\"\na = input()\nb = input()\nc = ''\nfor i in range(len(a)):\n if a[i] == b[i]:\n c += '0'\n else:\n c += '1'\nprint (c)", "a = input()\r\nb = input()\r\nlst3 =

Быстрый математик\r\nограничение по времени на тест2 seconds\r\nограничение по памяти на тест256 megabytes\r\nвводстандартный ввод\r\nвыводстандартный вывод\r\n\r\nШапур был очень способным студентом. Ему хорошо давались все науки: комбинаторика, алгебра, теория чисел, геометрия\r\nи все остальные. При этом он был не только умным, но и чрезвычайно быстрым! Он мог складывать 1018 чисел всего за одну секунду.\r\n\r\nОднажды в 230 году н. э. Шапур забеспокоился, не может ли кто-нибудь считать быстрее него. Он решил провести соревнование,\r\nв котором мог участвовать любой.\r\n\r\nНа соревновании он раздал участникам много разных пар чисел. Каждое число состояло из цифр 0 и 1. Участник в соответствие\r\nс данной ему парой чисел должен получить третье. Правило простое: i-я цифра ответа равна 1 тогда и только тогда, когда\r\ni-е цифры двух данных чисел отличаются. Иначе i-я цифра ответа — 0.\r\n\r\nШапур подготовил много чисел и сначала решил проверить собственную скорость. Он понял, что может выполнять эти операции\r\nдля чисел длины ∞ в мгновенье ока (длина числа — это количество цифр в нем)! Шапур всегда вычисляет абсолютно верно,\r\nи от участников своего соревнования ждет того же. Он честный человек, поэтому никогда не даст никому слишком большие\r\nчисла, и он всегда дает одному человеку числа одинаковой длины.\r\n\r\nСейчас вы примете участие в соревновании Шапура. Посмотрим, кто быстрее!\r\n\r\nВходные данные\r\nВходные данные состоят из двух строк. В каждой содержится одно число. Гарантируется, что числа состоят только из цифр\r\n0 и 1 и имеют одинаковую длину. Числа могут начинаться с 0.

He\n# could manage to sum 1018 numbers in a single second.\n\n# One day in 230 AD Shapur was trying to find out if any one can\n# possibly do calculations faster than him. As a result he made a very\n# great contest and asked every one to come and take part.\n\n# In his contest he gave the contestants many different pairs of\n# numbers. Each number is made from digits 0 or 1. The contestants\n# should write a new number corresponding to the given pair of\n# numbers. The rule is simple: The i-th digit of the answer is 1 if\n# and only if the i-th digit of the two given numbers differ. In the\n# other case the i-th digit of the answer is 0.\n\n# Shapur made many numbers and first tried his own speed. He saw that\n# he can perform these operations on numbers of length ∞ (length of a\n# number is number of digits in it) in a glance! He always gives\n# correct answers so he expects the contestants to give correct\n# answers, too. He is a good fellow so he won't give anyone very big\n# numbers and he always gives one person numbers of same length.\n\n# Now you are going to take part in Shapur's contest.

Ultra-Fast Mathematician\r\ntime limit per test2 seconds\r\nmemory limit per test256 megabytes\r\ninputstandard input\r\noutputstandard output\r\nShapur was an extremely gifted student. He was great at everything including Combinatorics, Algebra, Number Theory, Geometry, Calculus, etc. He was not only smart but extraordinarily fast! He could manage to sum 1018 numbers in a single second.\r\n\r\nOne day in 230 AD Shapur was trying to find out if any one can possibly do calculations faster than him. As a result he made a very great contest and asked every one to come and take part.\r\n\r\nIn his contest he gave the contestants many different pairs of numbers. Each number is made from digits 0 or 1. The contestants should write a new number corresponding to the given pair of numbers. The rule is simple: The i-th digit of the answer is 1 if and only if the i-th digit of the two given numbers differ. In the other case the i-th digit of the answer is 0.\r\n\r\nShapur made many numbers and first tried his own speed. He saw that he can perform these operations on numbers of length ∞ (length of a number is number of digits in it) in a glance! He always gives correct answers so he expects the contestants to give correct answers, too. He is a good fellow so he won't give anyone very big numbers and he always gives one person numbers of same length.\r\n\r\nNow you are going to take part in Shapur's contest. See if you are faster and more accurate.\r\n\r\nInput\r\nThere are two lines in each input. Each of them contains a single number. It is guaranteed that the numbers are made from 0 and 1 only and that their length is same. The numbers may start with 0. The length of each number doesn't exceed 100.\r\n\r\nOutput\r\nWrite one line — the corresponding answer. Do not omit the leading 0s.\r\n\r\nExamples\r\ninputCopy\r\n1010100\r\n0100101\r\noutputCopy\r\n1110001\r\ninputCopy\r\n000\r\n111\r\noutputCopy\r\n111\r\ninputCopy\r\n1110\r\n1010\r\noutputCopy\r\n0100\r\ninputCopy\r\n01110\r\n01100\r\noutputCopy\r\n00010\r\n'''\r\nINPUT_A

One day Vasya decided to watch a match of his favorite hockey team. And, as the boy loves hockey very much, even more than physics, he forgot to do the homework. Specifically, he forgot to complete his physics tasks. Next day the teacher got very angry at Vasya and decided to teach him a lesson. He gave the lazy student a seemingly easy task: You are given an idle body in space and the forces that affect it. The body can be considered as a material point with coordinates (0; 0; 0). Vasya had only to answer whether it is in equilibrium. \"Piece of cake\" — thought Vasya, we need only to check if the sum of all vectors is equal to 0. So, Vasya began to solve the problem. But later it turned out that there can be lots and lots of these forces, and Vasya can not cope without your help. Help him.
