1910. Remove All Occurrences of a Substring
Medium
30 Points
String
Stack
Simulation
Given two strings s and part, perform the following operation on s until all occurrences of the substring part are removed:
Return s after removing all occurrences of part.
A substring is a contiguous sequence of characters in a string.
Examples
Example 1
Input: s = "daabcbaabcbc", part = "abc"
Output: "dab"
Explanation: The following operations are done:
- s = "daabcbaabcbc", remove "abc" starting at index 2, so s = "dabaabcbc".
- s = "dabaabcbc", remove "abc" starting at index 4, so s = "dababc".
- s = "dababc", remove "abc" starting at index 3, so s = "dab".
Now s has no occurrences of "abc".
Example 2
Input: s = "axxxxyyyyb", part = "xy"
Output: "ab"
Explanation: The following operations are done:
- s = "axxxxyyyyb", remove "xy" starting at index 4 so s = "axxxyyyb".
- s = "axxxyyyb", remove "xy" starting at index 3 so s = "axxyyb".
- s = "axxyyb", remove "xy" starting at index 2 so s = "axyb".
- s = "axyb", remove "xy" starting at index 1 so s = "ab".
Now s has no occurrences of "xy".
Constraints
1 <= s.length <= 1000
1 <= part.length <= 1000
s and part consists of lowercase English letters.
