Problem 1: Even? Odd? [25 points] [Rob Kolstad, 2009]

Bessie's cruel second grade teacher has assigned a list of N (1 <= N <= 100) positive integers I (1 <= I <= 10^60) for which Bessie must determine their parity (explained in second grade as "Even... or odd?"). Bessie is overwhelmed by the size of the list and by the size of the numbers. After all, she only learned to count recently.

Write a program to read in the N integers and print 'even' on a single line for even numbers and likewise 'odd' for odd numbers.

POINTS: 25

PROBLEM NAME: evenodd

INPUT FORMAT:

  • Line 1: A single integer: N
  • Lines 2..N+1: Line j+1 contains I_j, the j-th integer to determine
       even/odd

SAMPLE INPUT (file evenodd.in):

2 1024 5931

INPUT DETAILS:

Two integers: 1024 and 5931

OUTPUT FORMAT:

  • Lines 1..N: Line j contains the word 'even' or 'odd', depending on
       the parity of I_j

SAMPLE OUTPUT (file evenodd.out):

even odd

OUTPUT DETAILS:

1024 is eminently divisible by 2; 5931 is not



我真的不是分割线------------------

Bessie那惨无人道的二年级老师搞了一个有 N (1 <= N <= 100) 个正整数 I (1 <= I <= 10^60) 的表叫Bessie去判断“奇偶性”(这个词语意思向二年级的学生解释,就是“这个 数是单数,还是双数啊?”)。Bessie被那个表的长度深深地震精到了,竟然跟栋栋的泛做表 格一样多道题!!!毕竟她才刚刚学会数数啊。

写一个程序读入N个整数,如果是双数,那么在独立的一行内输出"even",如果是单数则类似 地输出"odd".

分值: 25

题目名称: evenodd

输入格式:

  • 第一行: 一个单独的整数: N
  • 第2到第N+1行: 第j+1行有第j个需要判断奇偶性的整数。

样例输入 (文件:evenodd.in):

2 1024 5931

输入细节:

两个整数: 1024和5931

输出格式:

  • 第1..N行: 第j行根据第j个整数的奇偶性输出一个单词"even"或者"odd"

样例输出 (文件 evenodd.out):

even odd

输出格式:

1024可以被2整除; 而5931不可以。
