Array | Adding Ones | GeeksforGeeks | Practice in python

You start with an array A of size N. Also, A[i] = 0 for i = 1 to N. You will be given K positive integer. Let s be one of these integers, you have to add 1 to all A[i], for i >= j. Your task is to print the array A after all these K updates are done.

     t = int(input())                                           

     for i in range(t):

         n,m=list(map(int,input().split()))

         a=[0]*n

         arr=list(map(int,input().split()))

         for j in range(m):

             for j in range(arr[j]-1,int(n)):

                 a[j] += 1

     

         print(*a)
