Ques. To print the trapezium pattern?

Please also post your code in the comments in different languages or same languages with short or better time complexity code.

If N = 4
1*2*3*4*17*18*19*20
  5*6*7*14*15*16
    8*9*12*13
      10*11
If n = 5
1*2*3*4*5*26*27*28*29*30
  6*7*8*9*22*23*24*25
    10*11*12*19*20*21
      13*14*17*18
        15*16
If N = 2

    In Python:-

    input1 = int(input(“Enter the range:”))
    sum = 0
    total = (input1*(input1+1))
    count = total
    for i in range(input1):
    print(” “*(i),end=””)
    for k in range(input1,i,-1):
    sum += 1
    print(sum,end=”*”)
    count = total – sum
    for j in range(input1,i,-1):
    count += 1
    if(j==i+1):
    print(count,end=””)
    else:
    print(count,end=”*”)
    print()
