[FEATURE REQUEST] <title>find first previous smaller element for each element in an array using stack #4540
Closed as not planned
Description
What would you like to Propose?
Given an array "input" you need to print the previous smaller element for each element in that array.
For a given element x of an array, the previous smaller element of that element is the
first smaller element to the left side of it. If no such element is present print -1.
Issue details
like there were already codes for next greater and next smaller element present in the stack folder, I felt the lack of the code for previous smaller element, so decided to work on the same.
