Problem Description Write a program to determine whether a word is a palindrome. A palindrome is a sequence of characters that is identical to the string when the characters are placed in reverse order. For example, the following strings are palindromes: “ABCCBA”, “A”, and “AMA”. The following strings are not palindromes: “HELLO”, “ABAB” and “PPA”.
Input The input file will consist of up to 100 lines, where each line contains at least 1 and at most 52 characters. Your program should stop processing the input when the input string equals “STOP”. You may assume that input file consists of exclusively uppercase letters; no lowercase letters, punctuation marks, digits, or whitespace will be included within each word.
Output A single line of output should be generated for each string. The line should include “#”, followed by the problem number, followed by a colon and a space, followed by the string “YES” or “NO”.
Sample Input
ABCCBA
A
HELLO
ABAB
AMA
ABAB
PPA
STOP
Sample Output
#1: YES
#2: YES
#3: NO
#4: NO
#5: YES
#6: NO
#7: NO
我想shi的心都有了，那天考试连A三次都没过，思路也没啥问题啊！事后突然发现大写的O不知怎么的被写写成小写的了。哎，不然名次就上升好几名了
