? Because the number of 1 per 3bit is up to 3. Therefore, the following addition does not have a rounding problem, because 3 + 3 = 6, less than 8, does not produce a carry.TMP + (TMP >> 3)-This is the addition of adjacent groups, note that there will be repeated additions to the part, such as TMP = 659 = 001 010 010 011, tmp >> 3 = 000 001 010 010, added001 010 010 011000 001 010 010---------------------001
Title Requirements:Given an array of integers and a target value, find the two numbers in the array and the target values.You can assume that each input corresponds to only one answer, and that the same element cannot be reused.Ideas:Sum must be, to ask two numbers, you need two pointers, two pointers a large one small do not want to wait, first let the small pointer do not move, let the large pointer move backwards, know that appears greater than or
//compares whether the lowest bit is 1, the complexity O (Logn), is only suitable for positive numbers, and when it is negative, there will be a dead loopfunctionGetOne (n) {varc = 0; while(n) {if(n1) {C++; } N>>= 1; } console.log (c);}functionGetOne (n) {varc = 0; for(vari = 1; I I ) { if(I N) {c++; }} console.log (c);}//quickly remove the highest bit 1func
use the sort () function, directly using the Arrays.sort () function array of small to large order, each time the results are directly output.At the same time, I need to clear the results after the loop, I use the Arrays.fill () function, with ' "" to fill, but there are insufficient places, will be emptied after the form of 0 exist, the length of the array has not changed, so need me to further improve, the final evaluation results still have a run timeout!! , for informational purposes onlyIn
Given a binary array, find the maximum number of consecutive 1s in this array.Example 1:Input: [1,1,0,1,1,1] Output: 3Explanation: the first and digits or the last three digits is consecutive 1s. The maximum number of consecutive 1s is 3.note:
The input array would be only contain and 0
Problem descriptionFor a given array, find 2 numbers, they meet 2 numbers and equals a specific number, and return the index of these two numbers. (starting from 1)Given an array of integers, find the numbers such that they add up to a specific target number.The function twosum should return indices of the numbers such

Train of Thought Analysis:1) First, determine the number of prime numbers. A prime number is a number that can be divisible by 1 and itself, but cannot be divisible by a number smaller than 1
Version1: Find a number in an array that appears only once, and the other numbers appear two times: all numbers are different or the resulting result is only one occurrence. Version2: Find two occurrences of a number in an array, the other numbers appear two times: The result of all the numbers is X=a^b, the index is t

Definition of prime number:
Refers to the number of natural numbers greater than 1 that cannot be divisible by other natural numbers except 1 and the integer itself.
1 and 0 are not prime or composite. Prime numbers are two concepts that are relative to composite, and they

Description
A game is popular in a country. The game rule is: in a pile of balls, each ball has an integer number I (0
Input
The first row has two integers, m, n (0 Next, enter m + n integers. The first m represents the number I of the M balls, and the last n represent
I. Source and description of the problemToday saw July's microblog, found the July problem, there is this problem, very interesting.The size of any two adjacent elements in array a differs by 1, and is given the array A and target integer t to find the position of T in array A. Arrays: [1,2,3,4,3,4,5,6,5], locate 4 in the array.two. Algorithm analysis and implementationthe worst time complexity of the topic
