An important concept in computer science that refers to first element on the right side of a given element that is greater than that element in the array. In case no greater element exists, next greater element is considered as -1.
Get the job done with a straightforward approach. This method solves the problem by using two nested loops and finding the first element to the right that's greater than each element A[i].Ready to see how it works? Check out the algorithm!
Push the first element of the array into the stack, iterate through all elements from 1 to N - 1. If the current index value < value at top of stack, push it. And, if the value is greater, pop remaining elements.
