Implement a function fill(array, value, start = 0, end = array.length) that fills elements of an array with a specified value from start index up to, but not including, end index.

• array: The array to modify.
• value: The value to fill the array with.
• start (optional): Start index (inclusive). Defaults to 0.
• end (optional): End index (exclusive). Defaults to array.length.

Example

fill([1, 2, 3, 4], 0); // [0, 0, 0, 0]
fill([1, 2, 3, 4], 5, 1, 3); // [1, 5, 5, 4]
