NOIP2009年普及组阅读程序填写结果题：
#include <iostream>
usingnamespacestd;
constint maxn = 50;
void getnext(char str[]) {
int l = strlen(str), i, j, k, temp;
k = l - 2;
while (k >= 0 && str[k] > str[k + 1]) k--;
i = k + 1;
while (i < l && str[i] > str[k]) i++;
temp = str[k];
str[k] = str[i - 1];
str[i - 1] = temp;
for (i = l - 1; i > k; i--)
for (j = k + 1; j < i; j++)
if (str[j] > str[j + 1]) {
temp = str[j];
str[j] = str[j + 1];
str[j + 1] = temp;
}
return;
