UVa 1585

上代码  直接统计即可

import java.util.*;

public class Main1585 {

	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		int n = scan.nextInt();
		String str;
		while(n-- > 0) {
			str = scan.next();
			int len = str.length();
			int count = 0;
			for(int i=0; i<len; i++) {
				int cnt = 0;
				if(str.charAt(i) == 'O') {
					cnt = 1;
					for(int j=i+1; j<len; j++) {
						if(str.charAt(j) == 'O') {
							cnt ++;
						}
						else break;
					}
				}
				count += cnt;
			}
			System.out.println(count);
		}
	}
}
