01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第144题(顺位题号是633)。给定一个非负整数c,判断是否存在两个整数a和b,使得a的平方与b的平方之和等于c。例如: 输入:5 输出:true 说明:1 x 1 + 2 x 2 = 5 输入:3 输出:false 本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7...
// display the sum of natural number printf("\n Sum of the first %d number is: %d", num, sum); getch(); } Output:Enter a positive number: 25 Sum of the first 25 number is: 325 Using while LoopLet's create a C program that determines the sum of n natural numbers using wh...
import java.util.Scanner; class ExArrayElementSum { public static void main(String args[]) { // create object of scanner. Scanner s = new Scanner(System.in); int n, sum = 0; // enter number of elements you want. System.out.print("Enter the elements you want : "); // read ...
We have an array A of integers, and an array queries of queries. For the i-th query val = queries[i][0], index = queries[i][1], we add val to A[index]. Then, the answer to the i-th query is the sum of the even values of A. ...
You are given one more array of size K. This array is called a multiplier array. First element will get multiplied with the first number chosen. Your task is to maximise the sum of the numbers. In short : A : [2,13,7,15]
