Statement
Implement a next_greater_element() function that takes a list of integers, lst, as input and returns the next greater number for every element in the list.
The next greater number for a number lst[i] is the first number to its right that is greater than lst[i]. If no such number exists, return -1 for this number.
Constraints:
-
lst.length
