memcmp(const void *buf1, const void *buf2, unsigned int count)可以比较两个串相等

其中count是内存大小,不是数组大小,要用sizeof()得出
#include <iostream> #include <string> #include <cstring> #include <cstdlib> #include <cstdio> #include <cmath> #include <algorithm> #include <stack> #include <cctype> using namespace std; #define mem(a,b) memset(a,b,sizeof(a)) #define pf printf #define sf scanf #define spf sprintf #define debug printf("!\n") #define INF 10000 #define MAXN 5010 #define MAX(a,b) a>b?a:b #define blank pf("\n") #define LL long long char a[110],b[110]; int ac[26],bc[26]; int main() { while(~sf("%s%s",a,b)) { int i,j; mem(ac,0); mem(bc,0); int al = strlen(a); int bl = strlen(b); if(al!=bl) { puts("NO"); continue; } for(i=0;i<al;i++) { ac[a[i]-'A']++; bc[b[i]-'A']++; } sort(ac,ac+26); sort(bc,bc+26); if(!memcmp(ac,bc,sizeof(ac))) puts("YES"); else puts("NO"); mem(a,0); mem(b,0); } }
