I tried these solutions => brute force; brute force with Euclidean algorithm; By calculating the frequency of all the divisors of each … WebThe GCD table G of size n × n for an array of positive integers a of length n is defined by formula. Let us remind you that the greatest common divisor (GCD) of two positive integers x and y is the greatest integer that is divisor of both x and y, it is denoted as . For example, for array a = {4, 3, 6, 2} of length 4 the GCD table will look as ...

WebJun 15, 2024 · The simplest approach to solve the problem is to generate all possible pairs from [1, N] and calculate GCD of each pair. Finally, print the maximum GCD obtained. Since all the pairs are distinct, then, for any pair {a, b} with GCD g, either of a or b is greater than g. Considering b to be the greater number, b > 2g, since 2g is the smallest ...

WebThe first line of each test case contains the integers n and k ( 1 ≤ n ≤ 2 ⋅ 10 5, 1 ≤ k ≤ n) — the length of the array a and the minimum amount of times each number in the range [ l, r] should appear respectively. Then a single line follows, containing n integers describing the array a ( 1 ≤ a i ≤ 10 9 ). It is guaranteed that ... Web1662H - Boundary - CodeForces Solution. Bethany would like to tile her bathroom. The bathroom has width w centimeters and length l centimeters. If Bethany simply used the basic tiles of size 1 × 1 centimeters, she would use w ⋅ l of them.
