2017中南大学暑期集训day1 : debug&STL-A

A - Surprising Strings

题意就是给你一个字符串,例如ZGBG,有一种称谓叫D-unique

这个字符串 在D=0时, 有三个子串 ZG GB BG,因为这三个都不同,也就是unique,所以ZGGB是 0-unique;

同理               D=1时,有两个子串ZB GG也是不同,所以ZGGB是 1-unique;

                      D=2时,只有一个子串ZG,独一无二,所以ZGGB是 2-unique;

ince these three pairs are all different,Thus ZGBG is surprising.因为这三个都是独一无二的,所以满足题目要求;

用map建立每个子串与数字的联系来统计,很方便。
