Given an array of numbers, create a new array where each element represents the next strictly greater element to the right of the corresponding element in the input array x. If there is no next greater element, put -1.
For example, given x = [1 3 2 4], the output should be [3 4 4 -1] because:
- The next greater element to 1 is 3.
- The next greater element to 3 is 4.
- The next greater element to 2 is 4.
- There is no next greater element to 4, so it is -1.

Just like #60186, this is a misleading problem as well.
Will be interesting to find an efficient method for it - both speed and memory wise.
