How to find the maximum length of a subarray?
Maximum Length of Repeated Subarray Given two integer arrays nums1 and nums2, return the maximum length of a subarray that appears in both arrays. Input: nums1 = [1,2,3,2,1], nums2 = [3,2,1,4,7] Output: 3 Explanation: The repeated subarray with maximum length is [3,2,1].
How to solve the problem of the longest alternating subarray?
Approach: The following steps are followed to solve the problem: Initially initialize cnt as 1. Iterate among the array elements, check if it has an alternate sign. Increase the cnt by 1 if it has a alternate sign. If it does not has an alternate sign, then re-initialize cnt by 1.
How to update subarray with sum greater than given value?
A simple solution is to use two nested loops. The outer loop picks a starting element, the inner loop considers all elements (on right side of current start) as ending element. Whenever sum of elements between current start and end becomes more than the given number, update the result if current length is smaller than the smallest length so far.
How many times can you decrement a subarray?
You can decrement elements of A up to k times, with the goal of producing a consecutive subarray whose elements are all equal. Return the length of the longest possible consecutive subarray that you can produce in this way.
Given an array of n integers. The task is to find the maximum length of the sub-array such that absolute difference between all the consecutive elements of the sub-array is either 0 or 1. {5, 6} and {7, 6, 5} are the only valid sub-arrays.
How to return longest subarray of 1’s after deleting one element?
Given a binary array nums, you should delete one element from it. Return the size of the longest non-empty subarray containing only 1’s in the resulting array. Return 0 if there is no such subarray. Input: nums = [1,1,0,1] Output: 3 Explanation: After deleting the number in position 2, [1,1,1] contains 3 numbers with value of 1’s.
When do you have contiguous elements in a subarray?
If all elements are distinct, then a subarray has contiguous elements if and only if the difference between maximum and minimum elements in subarray is equal to the difference between last and first indexes of subarray. So the idea is to keep track of minimum and maximum element in every subarray.
