Question 338. Counting Bits Question: Given a non negative integer number num. For every numbers i in the range 0 ≤ i ≤ num calculate the number of 1’s in their binary representation and return them
Given a non negative integer number num. For every numbers i in the range 0 ≤ i ≤ num calculate the number of 1’s in their binary representation and return them as an array. Example: For num = 5 you
给你一个整数 n ,对于 0 <= i <= n 中的每个 i ,计算其二进制表示中 1 的个数 ,返回一个长度为 n + 1 的数组ans 作为答案。 class Solution {public:vector<int> countBits(int n) {//题目要求长度为 n + 1 的数组 ansvector<int> ans(n + 1);//设置初始值,已知0的二进制1的个数
Given a non negative integer number num. For every numbers i in the range 0 ≤ i ≤ num calculate the number of 1's in their binary representation and return them as an array. Example: For num = 5 you
题目描述 给你一个整数 n ,对于 0 <= i <= n 中的每个 i ,计算其二进制表示中 1 的个数 ,返回一个长度为 n + 1 的数组 ans 作为答案。 问题分析 因为每一个数在计算机内存部的存储方式都是二进制的存储方式,所以我们只需要每一次将数字使用右移操作符进行移一位,然后查看这一位是否为1即可,是1就统计上,这种方法查看一个数字的每一位需要 l o g 2 n log_2n
