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,…

problem 696. Count Binary Substrings 题意:具有相同个数的1和0的连续子串的数目: solution1:还不是特别理解... 遍历元数组,如果是第一个数字,那么对应的ones或zeros自增1.然后进行分情况讨论,如果当前数字是1,然后判断如果前面的数字也是1,则ones自增1,否则ones重置为1.如果此时zeros大于ones,res自增1.反之同理,如果当前数字是0,然后判断如果前面的数字也是0,则zeros自增1,否则zeros重置为1.如果此时one…
