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.

Example 1:

Input: s = "84532", t = "34852"
Output: true
Explanation: You can transform s into t using the following sort operations:
"84532" (from index 2 to 3) -> "84352"
"84352" (from index 0 to 2) -> "34852"

Example 2:

Input: s = "34521", t = "23415"
Output: true
Explanation: You can transform s into t using the following sort operations:
"34521" -> "23451"
"23451" -> "23415"

Example 3:

Input: s = "12345", t = "12435"
Output: false

Constraints:

• s.length == t.length
• 1 <= s.length <= 105
• s and t consist of only digits.
