Program to Print Mirror Image of Sine-Wave Pattern

Give Height and Width of a Wave to print the pattern

Examples:

Input : wave_height=5
        wave_length=10
Output :

>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>
  >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>  
    >>        >>        >>        >>        >>        >>        >>        >>        >>        >>    
  >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>    >>  >>  
>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>>>      >>



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.
