Remove Array Part

Description

Remove a part of a given array between given 0-based indexes l and r (inclusive).

Example

For inputArray = [2, 3, 2, 3, 4, 5], l = 2, and r = 4, the output should be removeArrayPart(inputArray, l, r) = [2, 3, 5].

Input/Output

  • [execution time limit] 4 seconds (js)

  • [input] array.integer inputArray

    Guaranteed constraints:
    2 ≤ inputArray.length ≤ 104,
    -105 ≤ inputArray[i] ≤ 105.

  • [input] integer l

    Left index of the part to be removed (0-based).

    Guaranteed constraints:
    0 ≤ l ≤ r.

  • [input] integer r

    Right index of the part to be removed (0-based).

    Guaranteed constraints:
    l ≤ r < inputArray.length.

  • [output] array.integer
