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

昨天看了编程珠玑第一章的内容, 发现bitmap对于统计某一个范围内的整数个数效率很高, 就自己实现了一下: 这是原始的bitmap, 用于统计0~maxSize是否出现, 也可以用于排序 public class BitMap { private int[] arr ; private final int mask = 0X1F ; //用于表示偏移量 private final int shift = 5 ; //用于表示index处于arr的第几个 public BitMap(int ma
