Uva - 1585 - Score

Therefore, the score of ``OOXXOXXOOO" is 10 which is calculated by ``1+2+0+0+1+0+0+1+2+3".

You are to write a program calculating the scores of test results.

Input 

Your program is to read from standard input. The input consists of T test cases. The number of test cases Tis given in the first line of the input. Each test case starts with a line containing a string composed by `O' and `X' and the length of the string is more than 0 and less than 80. There is no spaces between `O' and `X'.

Output 

Your program is to write to standard output. Print exactly one line for each test case. The line is to contain the score of the test case.

The following shows sample input and output for five test cases.

Sample Input 

5 
OOXXOXXOOO 
OOXXOOXXOO 
OXOXOXOXOXOXOX 
OOOOOOOOOO 
OOOOXOOOOXOOOOX

Sample Output 

10 
9 
7 
55 
30

AC代码：

#include <stdio.h>
#include <string.h>
#define MAXN 85

int main()
{
	int T;
	char s[MAXN];
	scanf("%d", &T);
	while (T--) {
		scanf("%s", s);
		int n = strlen(s);
		// p=0表示上个字符是x
		int score = 0, p = 0, q = 1;
		for (int i = 0; i < n; i++) {
			// 不是很明确字母o是大写还是小写，两种情况都考虑
			if (s[i] == 'o' || s[i] == 'O') {
				if (p == 0) {
					score += q++;
					p = 1;
				}
				else {
					score += q++;
				}
			}
			else {
				p = 0;
				q = 1;
			}
		}
		printf("%d\n", score);
	}

	return 0;
}
