Python3

class Solution:
    def threeConsecutiveOdds(self, arr: List[int]) -> bool:
        cnt = 0
        for v in arr:
            if v & 1:
                cnt += 1
            else:
                cnt = 0
            if cnt == 3:
                return True
        return False

Java

class Solution {
    public boolean threeConsecutiveOdds(int[] arr) {
        int cnt = 0;
        for (int v : arr) {
            if (v % 2 == 1) {
                ++cnt;
            } else {
                cnt = 0;
            }
            if (cnt == 3) {
                return true;
            }
        }
        return false;
    }
}

C++

class Solution {
public:
    bool threeConsecutiveOdds(vector<int>& arr) {
        int cnt = 0;
        for (int v : arr) {
            if (v & 1)
                ++cnt;
            else
                cnt = 0;
            if (cnt == 3) return true;
        }
        return false;
    }
};

Go

func threeConsecutiveOdds(arr []int) bool {
    cnt := 0
    for _, v := range arr {
        if v%2 == 1 {
            cnt++
        } else {
            cnt = 0
        }
        if cnt == 3 {
            return true
        }
    }
    return false
}

TypeScript

function threeConsecutiveOdds(arr: number[]): boolean {
    let cnt = 0;
    for (const v of arr) {
        if (v & 1) {
            ++cnt;
        } else {
            cnt = 0;
        }
        if (cnt == 3) {
            return true;
