[Solution] Fake GCD solution codechef

Fake GCD solution codechef . You are given an integer NN. Output a permutation of values from 11 to NN that satisfies the following condition: gcd([1+A1,2+A2,3+A3,…,N+AN])>1gcd([1+A1,2+A2,3+A3,…,N+AN])>1 It can be proven that a solution always exists. If there are multiple permutations that can satisfy the condition, then output any one of them. As a reminder, A permutation of values from 11 to NN is an array containing integers from 11 to NN in any … Read more

Detect Squares Solution leetcode – You are given a stream of points on the X-Y plane. Design an algorithm that: Adds new points from the stream into a data structure. Duplicate points are allowed and should be treated as different points. Given a query point, counts the number of ways to choose three points from the data structure such that the three points and the query point form an axis-aligned square with positive area.

Longest Subsequence Repeated k Times Solution leetcode – You are given a string s of length n, and an integer k. You are tasked to find the longest subsequence repeated k times in string s.

You are given a string s of length n, and an integer k. You are tasked to find the longest subsequence repeated k times in string s. A subsequence is a string that can be derived from another string by deleting some or no characters without changing the order of the remaining characters. A subsequence seq is repeated k times in the string s if seq * k is a subsequence of s, where seq * k represents a string constructed … Read more
