内存限制65536 kB
代码长度限制16000 B
Given two strings S1 and S2, S = S1 - S2 is defined to be the remaining string after taking all the characters in S2 from S1. Your task is simply to calculate S1 - S2 for any given strings. However, it might not be that simple to do it fast.
Input Specification:
Each input file contains one test case. Each case consists of two lines which gives S1 and S2, respectively. The string lengths of both strings are no more than 10^4. It is guaranteed that all the characters are visible ASCII codes and white space, and a new line character signals the end of a string.
Output Specification:
For each test case, print S1 - S2 in one line.
Sample Input:
They are students.
aeiou
Sample Output:
Thy r stdnts.
解题思路
排除s2中字符输出即可AC代码
#include <cstdio> #include <cstring> char s[10005], aim[10005]; int main() { gets(s); gets(aim); int len = strlen(s); for (int i = 0; i < len; ++i){ if (NULL == strchr(aim, s[i])){ putchar(s[i]); } } return 0; }
