Function slice 

pub fn slice<T>(collection: &[T], start: isize, end: isize) -> Vec<T>
where
    T: Clone,

Returns a subset of the collection based on the provided start and end indices.

This function extracts a subset from the given collection starting at the specified start index and ending before the end index. If the start or end indices are negative, they are offset from the end of the collection. The function ensures that the resulting subset does not exceed the bounds of the original collection.

Time Complexity: O(n), where n is the number of elements in the subset.

Arguments

• collection - A slice of items from which to extract the subset.
• start - The starting index for the subset. Can be negative to indicate an offset from the end.
• end - The ending index for the subset. Can be negative to indicate an offset from the end.

Type Parameters

• T - The type of elements in the collection. Must implement Clone.

Returns

• Vec<T> - A vector containing the subset of elements.

let numbers = vec![1, 2, 3, 4, 5];
let result = slice(&numbers, 1, 3);
