Print Solid Rectangle Pattern

Given two integers n and m, print a solid rectangle pattern of stars with n rows and m columns. Each row has exactly m stars.

Examples:

Input: n = 3, m = 5

Output:

Input: n = 4, m = 2

Output:

Nested Loops Approach - O(n * m) Time and O(1) Space

The pattern can be printed using two nested loops.

• The outer loop iterates through the rows (1 to n)
• The inner loop iterates through the columns (1 to m)

A star (*) is printed for every cell. After printing all stars in a row, move to the next line to form the solid rectangle.

Total number stars printed is equal to n * m
