Vito wants to minimize the total distance to all of them and has blackmailed you to write a program that solves his problem. inputthe input consists of several test cases. the first line contains the number of test cases. for each test case you will be given the integer number of relatives r ( 0 < r < 500) and the street numbers (also integers) s1, s2, si, sr where they live ( 0 < si < 3 ). note that several relatives could live in the same street number. outputfor each test case your program must write the minimal sum of distances from the optimal vito's house to each one of his relatives. the distance between two street numbers si and sj is dij= |si-sj|.sample input22 2 43 2 4 6sample output24
