1 <= n <= 109 使用自带函数Integer.toBinaryString()就可以的,遍历确认接,下面是代码: classCode1016{publicstaticvoidmain(String[]args){String s="0110";int n=4;System.out.println(queryString(s,n));}publicstaticbooleanqueryString(String s,int n){for(int i=1;i<=n;i++){if(!s.contains(...
LeetCode 536. Construct Binary Tree from String You need to construct a binary tree from a string consisting of parenthesis and integers. The whole input represents a binary tree. It contains an integer followed by zero, one or two pairs of parenthesis. The integer represents the root's value...
今天介绍的是LeetCode算法题中Easy级别的第160题(顺位题号是693)。给定正整数,检查它是否具有交替位:即它的二进制数的任意两个相邻位总是具有不同的值。例如: 输入:5 输出:true 说明:5的二进制表示是:101 输入:7 输出:false 说明:7的二进制表示为:111。

Hi@Harrywithcode.I know you‘re troubled by this question.The core problem is what's the meaning of 2.10 and 2.9 in Math and this question. In Math 2.10 is equal to 2.1 So that 2.9 is absolutely greater than 2.10 In this question ...
一、 Introduction to Array Find Pivot Index 思路: 朴素想法是遍历每一个数,分别计算其左右的和是否相等,这样的时间复杂度是O(n^2)。高级一点的想法是先计算序列的和记为sum,再遍历每一个数p,记这个数左边的序列和为leftSum,只需判断leftSum是否和sum - leftSum - p相等即可。
