Given a list of integers, for each element, replace it with the minimum integer found in the sub-list to its strict right (excluding itself). The last element should be replaced with 'inf'. Return the modified list.
For example, if the input list is [17, 18, 5, 4, 6, 10], the output should be [4, 4, 4, 6, 10, inf].
Explanation:
  • For the first element, the minimum integer to its right is 4.
  • Similarly, for the second and third elements, the minimum integer to their right is 4.
  • For the fourth element, the minimum integer to its right is 6.
  • For the fifth element, the minimum integer to its right is 10.
  • Since there are no elements to the right of the last element, it's replaced with 'inf'.
