Description: The description of the problem: given an n-character string s, to determine whether it is a palindrome, set up a string s is: S: C1, C2, .... of Ci, Ci+1, ..... of Cn " P = (n/2), the string s to meet the following conditions. If n is even, then C1 = Cn, C2 = Cn-1, ...., of Cp 1 = Cp+2 of, Cp = Cp+1 if n is odd, then C1 = Cn, C2 = Cn-1, .... Cp-1 = Cp+3, Cp = Cp+2.
