1585. Check If String Is Transformable With Substring Sort Operations
Description
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"
.
- For example, applying the operation on the underlined substring in
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
andt
consist of only digits.
