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

<https://leetcode.com/problems/detect-pattern-of-length-m-repeated-k-or-more-times>

## Description

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.
```

**Example 4:**

```
**Input:** arr = [1,2,3,1,2], m = 2, k = 2
**Output:** false
**Explanation:** Notice that the pattern (1,2) exists twice but not consecutively, so it doesn't count.
```

**Example 5:**

```
**Input:** arr = [2,2,2,2], m = 2, k = 3
**Output:** false
**Explanation:** The only pattern of length 2 is (2,2) however it's repeated only twice. Notice that we do not count overlapping repetitions.
```

**Constraints:**

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