题意:给出两个字符串s1和s2(长度不超过1000),问s1是否包含s2中的所有字符,若包含,则输出Yes,并输出s1中多余的字符个数:若不完全包含,则输出No,并输出缺少的个数. 思路:定义数组int cnt[128],遍历字符串s1,记录各个字符出现的次数,cnt[i]表示i对应的字符出现的次数:然后遍历字符串s2,每访问一个字符,就把对应的cnt[i]减1,当遍历完了之后,若cnt[]均大于等于0,则说明s1含有s2的所有字符,输出Yes,以及strlen(s1)-strlen(s2):否…

题意: 输入两行字符串,如果第二行字符串包含于第一行字符串,输出"Yes"以及第一行字符串减去第二行字符串剩余的字符个数,否则输出"No"以及第二行字符串中不在第一行字符串中的字符个数(同一字符可能出现多次,对个数敏感). AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; string s1,s2; ],vis[]; i…
