Complete the function solveMeFirst to compute the sum of two integers. Function prototype: int solveMeFirst(int a, int b); where, a is the first integer input. b is the second integer input Return values sum of the above two integers

Simple Array Sum

Given an array of integers, find the sum of its elements. For example, if the array ar = [1,2,3], 1+2+3 = 6 , so return 6 . Function Description Complete the simpleArraySum function in the editor below. It must return the sum of the array elements as an integer. simpleArraySum has the following parameter(s): ar: an array of integers Input Format The first line contains an integer, n, denoting the size of the array. The second line contains n space-separated integers re

Compare the Triplets

Alice and Bob each created one problem for HackerRank. A reviewer rates the two challenges, awarding points on a scale from 1 to 100 for three categories: problem clarity, originality, and difficulty. The rating for Alice's challenge is the triplet a = (a[0], a[1], a[2]), and the rating for Bob's challenge is the triplet b = (b[0], b[1], b[2]). The task is to find their comparison points by comparing a[0] with b[0], a[1] with b[1], and a[2] with b[2]. If a[i] > b[i], then Alice is a

A Very Big Sum

In this challenge, you are required to calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large. Function Description Complete the aVeryBigSum function in the editor below. It must return the sum of all array elements. aVeryBigSum has the following parameter(s): int ar[n]: an array of integers . Return long: the sum of all array elements Input Format The first line of the input consists of an integer n

Diagonal Difference

Given a square matrix, calculate the absolute difference between the sums of its diagonals. For example, the square matrix arr is shown below: 1 2 3 4 5 6 9 8 9 The left-to-right diagonal = 1+ 5 + 9 = 15. .The right to left diagonal = 3 +5 +9 = 17 . Their absolute difference is |15-17| = 2 . . Function description Complete the diagonal difference function in the editor below. diagonalDifference takes the following parameter: int arr[n][m]: an array of integers

HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses, where developers compete by trying to program according to provided specifications. HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, JavaScript) and span multiple computer science domains. When a programmer submits a solution to a programming challenge, their submission is scored on the accuracy of their output. Programmers are then ranked globally on the HackerRank leaderboard and earn badges based on their accomplishments to drive competition among users.

can i unlock editorial after SOLVING? if it won't remove my score

a shopkeeper sells n items where the price of 1th item is is price(1). To maintain balance, the shopkeeper wishes to adjust the price of items such that the medin of price is exactly K. in one move, the shopkeeeper can increase or decrease the price of any item by 1, and the shopkeeper can perform this move any number of items find the minimum number of moves in which the median of prices becomes exactly k

hello useres Problem solving is the cornerstone of progress and innovation. It's the art of finding solutions, not dwelling on obstacles This ensures an engaging progression with increasing difficulty levels,

In the context of a return policy , troubleshooting code issues is like inspecting a returned product. It involves checking for discrepancies between expected and actual outcomes, using debugging tools as inspection aids, seeking guidance from resources or peers like consulting store policies, and aiming for a clear solution that addresses the problem effectively.

Why do I find this question wrong? How can I solve the second set of problem - 5 1

5 3 4 5 6 - in a single day with increasing order and K>=1.

There are 2 problems with equal difficulty, 5. So, say, 3 4 5 5 6. difference between them is 0. And, if we do 5 3 4 5 6 then the increasing order of difficulty is broken as the seconf problem has the rating of 3 (<5). One of them needs to be solved on another day, correct?

Am I comprehending incorrect ly?
