Program to Print Inverted Right Half Pyramid Pattern (Star Pattern)

Given an integer N, print N rows of an inverted right half pyramid pattern. In an inverted right half pattern of N rows, the first row has N number of stars, the second row has (N - 1) number of stars, and so on till the Nth row, which has only 1 star.

Approach

• Follow these steps to print the inverted right half pyramid pattern using two nested loops.
• Run the outer loop from i = 1 to N to control the rows.
• For each iteration of the outer loop, run the inner loop from j = 1 to N - i + 1.
• Print an asterisk (*) in each iteration of the inner loop.
• Print a newline after completing the inner loop.
• Continue until all N rows are printed, forming the inverted right half pyramid.

Time Complexity: O(N^2), where N is the number of rows in the pattern.
Auxiliary Space: O(1)
