AC代码1:
#include<stdio.h> #include<algorithm> using namespace std; int main(void) { char s[4]; while(~scanf("%s",s)) { sort(s,s+3); printf("%c %c %c\n",s[0],s[1],s[2]); } return 0; }
AC代码2:
#include<stdio.h> int main(void) { char a,b,c,t; while(scanf("%c%c%c",&a,&b,&c)!=EOF) { getchar(); if(a > b) { t = a; a = b; b = t; } if(a > c) { t = a; a = c; c = t; } if(b > c) { t = b; b = c; c = t; } printf("%c %c %c\n",a,b,c); } return 0; }
AC代码2中要注意getchar()吃掉空格。
