Right-Angled Number Triangle

Given an integer n, print a right-angled triangle of numbers with n rows. In the i-th row, print the sequence of numbers from 1 to i separated by a single space.

The task is to generate a triangle pattern where each row gradually increases the sequence of numbers. Use the following formula for the numbers in the i-th row:

\( \text{Row}_i = 1\, 2\, \dots \,, i \)

inputFormat

The input consists of a single integer n provided via standard input (stdin), where n represents the number of rows in the triangle. You can assume that n is a positive integer.

outputFormat

The output should print the right-angled triangle pattern. Each row of the triangle should contain consecutive numbers starting from 1 up to the row number, with each number separated by a single space. The result is printed to standard output (stdout).
