Give a string s, count the number of non-empty (contiguous) substrings that have the same number of 0's and 1's, and all the 0's and all the 1's in these substrings are grouped consecutively. Substrings that occur multiple times are counted the numbe…
696. Count Binary Substrings Input: "00110011" Output: 6 Explanation: There are 6 substrings that have equal number of consecutive 1's and 0's: "0011", "01", "1100", "10", "0011", and "01&qu…
696. 计数二进制子串 给定一个字符串 s,计算具有相同数量0和1的非空(连续)子字符串的数量,并且这些子字符串中的所有0和所有1都是组合在一起的. 重复出现的子串要计算它们出现的次数. 示例 1 : 输入: "00110011" 输出: 6 解释: 有6个子串具有相同数量的连续1和0:"0011","01","1100","10","0011" 和 "01". 请…
题目要求 Give a string s, count the number of non-empty (contiguous) substrings that have the same number of 0's and 1's, and all the 0's and all the 1's in these substrings are grouped consecutively. Substrings that occur multiple times are counted the…
利用group, 将每个连着的0或者1计数并且append进入group里面, 然后再将group里面的两两比较, 得到min, 并且加入到ans即可.   T: O(n)   S: O(n)  比较好理解 improve: 思路相同, 用pre和cur去将space节省到O(1) Code 1)  T: O(n)   S: O(n) class Solution: def countBinarySubstrings(self, s): group = [1] for i in range(1,…
