Given an integer array nums, return true if there exists a triple of indices (i, j, k) such that i < j < k and nums[i] < nums[j] < nums[k]. If no such indices exists, return false.
Example 1:
Input: nums = [1,2,3,4,5]
Output: true
Explanation: Any triplet where i < j < k is valid.
Example 2:
Input: nums = [5,4,3,2,1]
Output: false
Explanation: No triplet exists.
Example 3:
Input: nums = [2,1,5,0,4,6]
Output: true
Explanation: The triplet (3, 4, 5) is valid because nums[3] == 0 < nums[4] == 4 < nums[5] == 6.class Solution {
public boolean increasingTriplet(int[] nums) {
int first = Integer.MAX_VALUE;
int second = Integer.MAX_VALUE;
for (int num : nums) {
if (num <= first) {
first = num;
} else if (num <= second) {
second = num;
} else {
return true;
}
}
return false;
}
}wtf how can i override ☕
