Check If String Is Transformable With Substring Sort Operations

Given two strings s and t, transform string s into string t using the following operation any number of times:

• Choose a non-empty substring in s and sort it in place so the characters are in ascending order.
  • For example, applying the operation on the underlined substring in "14234" results in "12344".

Return true if it is possible to transform s into t. Otherwise, return false.

A substring is a contiguous sequence of characters within a string.
