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.
Flip all the bits (1->0 and 0->1) and return the result as an unsigned integer. Example n=9 (10) 9 (10)=1001 (2). We're working with 32 bits, so: 000000000000000000000000000001001 = 9 (10) 111111111111111111111111111110110 = 4294967286 (10) Return 4294967286.
An array is a type of data structure that stores elements of the same type in a contiguous block of memory. In an array, A, of size N, each memory location has some unique index, i (where 0<=i<N), that can be referenced as A [i] or Ai. Reverse an array of integers.
Problem Statement : 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.
Each tower is of height . The players move in alternating turns. In each turn, a player can choose a tower of height and reduce its height to , where and evenly divides . If the current player is unable to make a move, they lose the game.
Objective: In this challenge, we will learn some basic concepts of C that will get you started with the language. You will need to use the same syntax to read input and write output in many C challenges.
Given an array, of size n, reverse it. Example: If array, arr= [1.2.3.4,5] after reversing it, the array should be, arr= [5,4,3,2,1] ….
This is an to practice traversing a linked list. Given a pointer to the head node of a linked list, print each node's data element, one per line. If the head pointer is null (indicating the list is empty), there is nothing to print.
In this challenge, you must read an integer, a double, and a String from stdin, then print the values according to the instructions in the Output Format section below. To make the problem a little easier, a portion of the code is provided for you in the editor.
