The elements in G are always nonnegative, and gcd(0,0) returns 0. This syntax supports inputs of any numeric type. example [G,U,V] = gcd(A,B) also returns the Bézout coefficients, U and V, which satisfy: A.*U + B.*V = G. The Bézout coefficients are useful for solving ...

Here, two integers stored in variablesnum1andnum2are passed to thecompute_hcf()function. The function computes the H.C.F. these two numbers and returns it. In the function, we first determine the smaller of the two numbers since the H.C.F can only be less than or equal to the small...
Description: The problem has been asked in competitive programming platforms and the concept has been featured in interview/coding rounds of many tech companies.Problem Statement: You are given an array A of integers of size N. You will be given Q queries where each query is represented by ...

Most of the times, what you've seen in this post is quite enough all you need for doing multitasking and concurrent programming. However, keep in mind that there are GCD concepts not touched in this tutorial, or some others already discussed, but not seen up to the last detail. The purp...
Grand Central Dispatch, or GCD, is an extremely powerful tool. It gives you low level constructs, like queues and semaphores, that you can combine in interesting ways to get useful multithreaded effects. The C-based API used to be a bit arcane, but it’s been cleaned up as of Swift 3...

Mathematical algorithms are also a very important topic for programming interviews. In this article, you'll learn how to find GCD and LCM of two numbers using C++, Python, C, and JavaScript. How to Find the GCD of Two Numbers The greatest common divisor (GCD) or highest common factor (HC...
