字母顺序的编码的一个问题的C语言的程序的设计解决的办法，怎么做的呢？

Question

Problem Description
Given a string containing only 'A' - 'Z', we could encode it using the following method:

1. Each sub-string containing k same characters should be encoded to "kX" where "X" is the only character in this sub-string.

2. If the length of the sub-string is 1, '1' should be ignored.

Input
The first line contains an integer N (1 <= N <= 100) which indicates the number of test cases. The next N lines contain N strings. Each string consists of only 'A' - 'Z' and the length is less than 10000.

Output
For each test case, output the encoded string in a line.

Sample Input
2
ABC
ABBCCC

Sample Output
ABC
A2B3C

Answer 1

#include<stdio.h>
#include<string.h>

int main() {
    int n,count,len;
    char str[10001];
    scanf("%d", &n);
    for (int i = 0; i < n; ++i) {
        scanf("%s", &str);
        len = strlen(str);
        for (int j = 0; j < len; ++j) {
            count = 1;
            while (j<len&&str[j] == str[j + 1] && ++j) 
                count++;
            if (count > 1)printf("%d", count);
            printf("%c", str[j]);
        }
        printf("\n");
    }
    return 0;
}
