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