You are given an array matches where each element matches[i] = [winneri, loseri] indicates that player winneri defeated player loseri in a match. Your task is to return a list answer of size 2 where:
answer[0] contains the list of players who have never lost a match.answer[1] contains the list of players who have lost exactly one match.The players in both lists should be sorted in increasing order.
circles, where each element circles[i] = [xi, yi, ri] represents a circle with center at (xi, yi) and radius ri. The task is to find the number of lattice points that lie inside at least one of the given circles. A lattice point is defined as a point with integer coordinates, and points lying on the circumference of a circle are also considered inside.cards where each element represents a card’s value. A matching pair of cards occurs when two cards have the same value. Your task is to find the minimum number of consecutive cards you need to pick to guarantee that you have a pair of matching cards. If it’s impossible to find a matching pair, return -1.nums and two integers k and p. Your task is to count the number of distinct subarrays where there are at most k elements divisible by p. A subarray is defined as a contiguous part of the array, and two subarrays are considered distinct if they differ in either length or at least one element.words, where each element of words[i] consists of lowercase English letters. In one operation, you can delete any word words[i] if it is an anagram of the previous word words[i-1]. Repeat this operation until no more deletions are possible. Your task is to return the list of words after performing all possible operations.
