1. mpstat命令 1.1 命令格式 mpstat [ -A ] [ -u ] [ -V ] [ -I { SUM | CPU | SCPU | ALL } ] [ -P { cpu [,...] | ON | ALL } ] [ interval [ count ] ] OPTIONS: -A: 等同...
1.题意说的是给定你n位的二进制串，除了成对的（就是指那些1的个数相同或0的个数相同的），那些不成对的数有几个。比如n为3时，可以有000,001,010,011,100,101,110,111这八种二进制数，其中001可以与010配对，011可以与110配对，剩余...
一、 基本类型特化流(数值流)在下面这段对流的操作的代码中，其实隐藏着一个问题: 装箱成本，每个原始类型都必须装箱成一个包装类型，如：Stream<Integer> integerStream = Stream.of(1, 2, 3);Integer sum = integerStream....
Mrs. Smith is trying to contact her husband, John Smith, but she forgot the secret phone number!
的信号为周期信号，否则为非周期信号，最小的T为基波周期；对于离散信号而言，对于任意的n均满足
Given an array nums of n integers and an integer target, find three integers in nums such that the sum is closest to target. Return the sum of the three integer...
Given a binary tree and a sum, find all root-to-leaf paths where each path's sum equals the given sum.
Given a m x n grid filled with non-negative numbers, find a path from top left to bottom right which minimizes the sum of all numbers along its path.
Given a binary tree and a sum, determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given sum.
Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.
