removeAtint

removeAtint is a term used to describe a function or method that removes the element at a specified index within a sequence of integers. It is commonly found in libraries and languages that operate on array-like containers, such as lists or vectors.

In typical usage, the index argument is integer and usually zero-based. The operation targets the element at that position and removes it from the container, shifting subsequent elements to fill the gap. The function may return the removed value, or it may signal success with no return value. If the index is out of bounds, implementations differ: some throw an exception, some return an error code, and others may return a sentinel value.

Time and space characteristics depend on the underlying container. For array-like structures, removeAtint generally executes in O(n) time due to the need to shift elements, and uses O(1) extra space. For linked lists, removal can be achieved in O(1) time given a valid reference to the node at the specified index, though locating that node may take O(n) time if random access is not supported.

Common edge cases include removing from an empty container, removing the first or last element, and handling invalid indices. Some designs retain the container’s capacity after removal; others may shrink internal storage.

Variants and related concepts include removeAt, erase, or splice, which apply to different data structures or programming paradigms. removeAtint is often complemented by insertAt or push operations to manage the composition of integer sequences.
