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
解题思路:
对于字母的输出不用排序输出,而且我们只要计算相邻的并且相同的字符就可以了,一旦不相同就输出。
程序代码:
#include<iostream> #include<cstdio> #include<cstring> using namespace std; int main() { int t,i,num; char str[10001]; scanf("%d",&t); while(t--) { scanf("%s",str); int len=strlen(str); num=1; for(i=0;i<len;i++) { if(str[i]==str[i+1]) num++; if(str[i]!=str[i+1]||str[i+1]=='\0') { if(num==1) printf("%c",str[i]); else { printf("%d%c",num,str[i]); num=1; } } } printf("\n"); } return 0; }
