    1566 - Detect Pattern of Length M Repeated K or More Times.

    Easy

    Given an array of positive integers arr, find a pattern of length m that is repeated k or more times.

    A pattern is a subarray (consecutive sub-sequence) that consists of one or more values, repeated multiple times consecutively without overlapping. A pattern is defined by its length and the number of repetitions.

    Return true if there exists a pattern of length m that is repeated k or more times, otherwise return false.

    Example 1:

    Input: arr = [1,2,4,4,4,4], m = 1, k = 3

    Output: true

    Explanation: The pattern (4) of length 1 is repeated 4 consecutive times. Notice that pattern can be repeated k or more times but not less.

    Example 2:

    Input: arr = [1,2,1,2,1,1,1,3], m = 2, k = 2

    Output: true

    Explanation: The pattern (1,2) of length 2 is repeated 2 consecutive times. Another valid pattern (2,1) is also repeated 2 times.

    Example 3:

    Input: arr = [1,2,1,2,1,3], m = 2, k = 3

    Output: false

    Explanation: The pattern (1,2) is of length 2 but is repeated only 2 times. There is no pattern of length 2 that is repeated 3 or more times.

    Constraints:

    • 2 <= arr.length <= 100
    • 1 <= arr[i] <= 100
    • 1 <= m <= 100
    • 2 <= k <= 100
