Pattern Printing – WIPR 001

Given an input value of N, complete the method printPattern so that program prints the pattern as given in example Input/Output.

Input Format:
The first line contains the value of the N.

Output Format:
The N lines contain the pattern as given in the example Input/Output.

Boundary Conditions:
4 <= N <= 100

Example Input/Output 1:
Input:
5

Output:
1
3 2
4 5 6
10 9 8 7
11 12 13 14 15
