A sine wave is a mathematical curve that oscillates between a maximum and minimum value, smoothly transitioning between positive and negative values. It is commonly used to represent periodic phenomena such as sound, light, and electrical signals.
Examples: Give the Height and Width of a Wave to print the pattern.
Input : wave_height=5
wave_length=10

Recommended: Please try your approach on {IDE} first, before moving on to the solution.
Approach
First, check the row and column where the elements are needed to be printed. Then, use nested for loops to print the elements in the corresponding order. Separate loops are kept to keep track of the wave_height and wave_length.Â
