You are given an array After processing each query you need to output the greatest common divisor (GCD) of all elements of the array a. Since the answer can be too large, you are asked to output it modulo 10^9+7. Input The first line contains two integers — n and q (1≤n,q≤...
You are given an array aa of length nn. You are asked to process qq queries of the following format: given integers ii and xx, multiply aiai by xx. After processing each query you need to output the greatest common divisor (GCD) of all elements of the array aa. Since the answer can...
collapse all G— Greatest common divisor real, nonnegative integer values Greatest common divisor, returned as an array of real nonnegative integer values. G is the same size as A and B, and the values in G are always real and nonnegative. G is returned as the same type as A and B....
From a DAG perspective, if we fix and select an arbitrary descendant of which is not , the sum of all values between and will always be . This property is essential to the function and allows it to be used in the Mobius Transform....
The second line containsnintegersai(2 ≤ ai ≤ 109) — elements of the array. Output Print a single number — the minimum cost of changes needed to obtain an array, such that the greatest common divisor of all its elements is greater than1. ...
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 ...
Greatest common divisor, returned as an array of real nonnegative integer values.Gis the same size asAandB, and the values inGare always real and nonnegative.Gis returned as the same type asAandB. IfAandBare of different types, thenGis returned as the nondouble type. ...
The first line of the input contains one integer n (1 ≤ n ≤ 2000) — the number of elements in the array. The second line contains n space separated integers a1, a2, …, an (1 ≤ ai ≤ 109) — the elements of the array. Output Print -1, if it is...
He wants to compress a into an array b of size n−1. To do this, he first discards exactly 2 (any two) elements from a. He then perfor...__gcd() 在翻别人的题解的时候偶然发现了这个函数,然后就去查了查,但是相关内容不多,__gcd(x,y);好像是GNU的内部函数,不是一个标准库里的函数...
