What is Next Greater Element Explained about?
The Next Greater Element (NGE) problem involves finding the first greater element to the right of each element in an array, with -1 assigned if no greater element exists. For example, in the array [4, 5, 2, 25], the NGE results in 5 for 4, 25 for 5, 25 for 2, and -1 for 25. A brute force solution using nested loops has a time complexity of O(n^2).
