Three Consecutive Odds
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
思路一：遍历
public boolean threeConsecutiveOdds(int[] arr) {
int n = 0;
for (int i : arr) {
if ((i & 1) == 1) {
n++;
} else {
n = 0;
}
if (n >= 3) return true;
}
return false;
}
