Returns void

delete

delete(startIndex: number, endIndex: number): StringBuilder

- Defined in packages/ds/src/classes/StringBuilder.ts:98
remarks
Complexity:

- Defined in packages/ds/src/classes/StringBuilder.ts:212
Builds and returns the character sequence represented by this object.
remarks
Complexity:
- Time complexity: O(N)
- Space complexity: O(N)
where:
- N: character count of this sequence
