Constraints:Input:First line contains T number of test cases. First line of each test case contains N, the number of friends Christie currently has and K ,the number of friends Christie decides to delete. Next lines contains popularity of her friends separated by space.Output:For each test case print N-K numbers which represent popularity of Christie friend's after deleting K friends.

There are N cows living in a cowshed, they all are standing in a line numbered form 1 to N in ascending order. The farmer is in funny mood so he made his mind to do something different, he decides to clean K cows from front and K cows from last and so on. A cow whose name is bessy trying to figure out last turn to get clean will belong to which number of cow, she needs your help to find this.Input Format :Input contains two lines , first line of input contains t - Number of test cases.Next t lines will contains two integers N and K - Number of cows and number of cows farmer is selecting from front and end.Output Format :Print the position of cow for every test case in a new line who will get the last turn.Example:Input:29 325 7Output:615Constraints:1. 1 <= T <= 102. 1 <= K<= N <= 10^5

Given an array of integers and a window size K, find the number of distinct elements in every window of size K of the given array.Input FormatThe first line of input contains T - the number of test cases. It's followed by 2T lines. The first line of each test case contains the N-size of the array and the K-size of the window. The second line contains N integers - elements of the array.Output FormatFor each test case, print the number of distinct elements in every window of size K, separated by a new line.Constraints30 points1 <= N <= 1001 <= K <= N70 points1 <= N <= 100001 <= K <= NGeneral Constraints1 <= T <= 1000-100 <= ar[i] <= 100ExampleInput35 3-2 -4 -2 4 -210 73 -4 -3 -4 -2 0 2 -2 6 017 13-5 -1 4 8 -5 -3 -4 7 4 -4 0 8 0 -2 3 2 5Output2 3 26 5 6 58 9 9 10 11
