1422. 分割字符串的最大得分

给你一个由若干 0 和 1 组成的字符串 s ,请你计算并返回将该字符串分割成两个 非空 子字符串(即  子字符串和  子字符串)所能获得的最大得分。

「分割字符串的得分」为  子字符串中 0 的数量加上  子字符串中 1 的数量。

示例 1:

输入:s = "011101"
输出:5 
解释:
将字符串 s 划分为两个非空子字符串的可行方案有:
左子字符串 = "0" 且 右子字符串 = "11101",得分 = 1 + 4 = 5 
左子字符串 = "01" 且 右子字符串 = "1101",得分 = 1 + 3 = 4 
左子字符串 = "011" 且 右子字符串 = "101",得分 = 1 + 2 = 3 
左子字符串 = "0111" 且 右子字符串 = "01",得分 = 1 + 1 = 2 
左子字符串 = "01110" 且 右子字符串 = "1",得分 = 2 + 1 = 3

示例 2:

输入:s = "00111"
输出:5
解释:当 左子字符串 = "00" 且 右子字符串 = "111" 时,我们得到最大得分 = 2 + 3 = 5

示例 3:

输入:s = "1111"
输出:3

提示:

  • 2 <= s.length <= 500
  • 字符串 s 仅由字符 '0' 和 '1' 组成。
package Solution1422;

class Solution {
	public int maxScore(String s) {
		int max = 0;
		for (int i = 0; i < s.length() - 1; i++) {
			String l = s.substring(0, i + 1);
			String r = s.substring(i + 1, s.length());
			int countl = 0;
			int countr = 0;
			for (int j = 0; j < l.length(); j++) {
				if (l.charAt(j) == '0') {
					countl++;
				}
			}
			for (int k = 0; k < r.length(); k++) {
				if (r.charAt(k) == '1') {
					countr++;
				}
			}
			if (countl + countr > max) {
				max = countl + countr;
			}
		}
		return max;
	}

	public static void main(String[] args) {

		Solution same = new Solution();

		String s = "00";

		System.out.println(same.maxScore(s));
	}

}
