1550. Three Consecutive Odds

Easy

Given an integer array arr, return true if there are three consecutive odd numbers in the array. Otherwise, return false.

Example 1:

Input: arr = [2,6,4,1]
Output:
 false
Explanation: There are no three consecutive odds.

Example 2:

Input: arr = [1,2,34,3,4,5,7,23,12]
Output:
 true
Explanation: [5,7,23] are three consecutive odds.

Constraints:

• 1 <= arr.length <= 1000

• 1 <= arr[i] <= 1000

解題

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