Program to print Sine-Wave Pattern
Last Updated :
02 May, 2025
Give the Height and Width of a Wave to print the Sine wave pattern
Examples:
Input : wave_height=5
wave_length=10
Output :
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
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.

Time complexity: O(h*l), Here h and l are wave height and wave length respectively.
Auxiliary space: O(1), As constant extra space is used.
How to print a sin wave of letters?

The approach is the same as above, now instead of using a single element, we use all of the 26 English alphabets in Upper_Case.
