{ "data": { "question": { "questionId": "2021", "questionFrontendId": "1910", "boundTopicId": null, "title": "Remove All Occurrences of a Substring", "titleSlug": "remove-all-occurrences-of-a-substring", "content": "

Given two strings s and part, perform the following operation on s until all occurrences of the substring part are removed:

\n\n\n\n

Return s after removing all occurrences of part.

\n\n

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

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "daabcbaabcbc", part = "abc"\nOutput: "dab"\nExplanation: The following operations are done:\n- s = "daabcbaabcbc", remove "abc" starting at index 2, so s = "dabaabcbc".\n- s = "dabaabcbc", remove "abc" starting at index 4, so s = "dababc".\n- s = "dababc", remove "abc" starting at index 3, so s = "dab".\nNow s has no occurrences of "abc".\n
\n\n

Example 2:

\n\n
\nInput: s = "axxxxyyyyb", part = "xy"\nOutput: "ab"\nExplanation: The following operations are done:\n- s = "axxxxyyyyb", remove "xy" starting at index 4 so s = "axxxyyyb".\n- s = "axxxyyyb", remove "xy" starting at index 3 so s = "axxyyb".\n- s = "axxyyb", remove "xy" starting at index 2 so s = "axyb".\n- s = "axyb", remove "xy" starting at index 1 so s = "ab".\nNow s has no occurrences of "xy".\n
