## You are given two binary strings SS and PP. You need to convert SS into PP using the following operation any number of times (possibly zero):

You are given two binary strings SS and PP. You need to convert SS into PP using the following operation any number of times (possibly zero): Pick three binary values XX, YY, and ZZ, such that at least one of them is equal to 11 and at least one of them is equal to 00. Then, pick three distinct indices ii, jj, and kk, and assign Si=XSi=X, Sj=YSj=Y, and Sk=ZSk=Z. Determine whether it’s possible … Read more

## An array is called lovely if the sum of absolute differences of each adjacent pair of elements is odd; formally, the array SS of size mm is lovely if ∑m−1i=1∑i=1m−1 |Si−Si+1||Si−Si+1| is odd.

An array is called lovely if the sum of absolute differences of each adjacent pair of elements is odd; formally, the array SS of size mm is lovely if ∑m−1i=1∑i=1m−1 |Si−Si+1||Si−Si+1| is odd. You are given an array AA of NN integers. You need to reorder the array in any manner such that the array becomes lovely. If there is no reordering operation that makes the array lovely, … Read more

## You are given an integer NN. Output a permutation of values from 11 to NN that satisfies the following condition:

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
