简单题。

附ac代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#define MAX 1000 + 2
char S[MAX];
char Alp[MAX];
char Dig[MAX];

int cmp(const void *a, const void *b){
	return *(char *)b - *(char *)a;
}

int main(){
	int t, alp, dig, len, i;
	scanf("%d", &t);
	while(t-- && scanf("%s", S)){
		memset(Alp, 0, sizeof(Alp));
		memset(Dig, 0, sizeof(Dig));
		len = strlen(S);
		alp = dig = 0;
		for(i = 0; i != len; ++i)
			if(isalpha(S[i]))
				Alp[alp++] = S[i];			
			else if(isdigit(S[i])) 
				Dig[dig++] = S[i];
		qsort(Dig, dig, sizeof(char), cmp);
		printf("%d ", alp);
		for(i = alp - 1; i >= 0; --i)
			putchar(Alp[i]);
		puts("");
		printf("%d %s\n", dig, Dig);
	}
	return 0;
