Print Number Pattern

Given a positive integer \(N\), print a number pattern where each row \(i\) contains \(i\) consecutive numbers starting from 1. The numbers are arranged in increasing order and each number in a row is separated by a single space.

For example, if \(N = 4\), the output should be:

1
2 3
4 5 6
7 8 9 10

Make sure that the output does not contain any extra spaces or blank lines.
