Why is HackerRank so hard? - Quora Over the course of the next few (actually many) days, I will be posting the solutions to previous Hacker Rank challenges. The Longest Alternating Subarray problem differs from the problem of finding the Longest Alternating subsequence. The catch is to use a feature of chosen programming language, which allows us operation with big numbers (e. g. BigInteger in Java) I created solution in: Java; All solutions are also available on my GitHub profile. This can be isolated such that we get the height of the triangle instead as. Return the maximum length of a subarray with positive product.. Solution is as follows: - Count the number of occurrences of the "balloon" letters in the input string - For "l" and "o", divide the count by 2 - If the balloon string is not fully covered, return 0 - Return the min number across all occurrences Code is below, cheers, ACC. For examples, string = "00111", the long substring is 00111 while count of 0 is 2 and count of 1 is 3. 13 min read Powered by Ghost. def arrayManipulation (n, queries): arr = [0]*n for i in queries: for j in range (i [0], i [1] + 1): arr [j - 1] += i [2] return max (arr) We loop over the rows in the query, and then sub-loop over the elements of the array than need summation.

Here the estimation of gravity is so much that even light can't receive in return. A naive approach will be to be traverse in the array and use hashing for every sub-arrays, and check for the longest sub-array possible with no more than K distinct elements.. An efficient approach is to use the concept of two pointers where we maintain a hash to count for occurrences of elements. Data-driven farming is the ability to map every farm in the world and overlay it with lots and lots of data for example, what is our soil moisture level maybe six inches below the ground or maybe the nutrition level varying throughout the field.
