arrays probably require a different solution. 5.3 THE SPARSE TABLE METHOD A less known, but worthwhile, improvement upon the full table method is the sparse table approach outlined in the online forum GeeksForGeeks [6]. We were unaware of this method until performing our literature search (and we did not find
Given 2 positive integers N and K and an array arr[], the task is to find whether it is possible to choose a non-empty subarray of the array such that the subarray contains exactly K even integers. Therefore, we cannot choose a subarray with K = 3 even numbers.
Is the set of distinct elements in the subarray [a_i, \ldots, a_j] equal to the set of elements in [a_k,\ldots,a_l] I want each query to be answered fast, in something like O(\log n), O(\log^2 n). I have been trying a lot of different techniques, including segment trees, polynomial hashing but none of them are working for me.

This approach takes O(n 3) time as subarray sum is calculated in O(1) time for each of n 2 subarrays and it takes O(n) time to print a sub-array.. 2. Hashing. We can also use hashing to find subarrays with given sum in an array by using a map of vector or a multi-map for storing end index of all subarrays having given sum.
$\begingroup$ There is: all subarrays contain at least one unique element, so your answer is wrong. WLOG let it be the first element that is unique and no more unique exists, then any subarray without first element fail. $\endgroup$ – Evil Oct 7 at 13:56

Let's say that we can find a hash function, h(k), which maps most of the keys onto unique integers, but maps a small number of keys on to the same integer. If the number of collisions (cases where multiple keys map onto the same integer), is sufficiently small, then hash tables work quite well and give O(1) search times.
Jun 01, 2016 · First, you can’t use 2 or more loops to get all subarrays. Second, there are totally 2^N subarrays. The most important lesson here – whenever you see issues like this (can’t use loops to check all possibilities or an exponential number of candidates), you should immediately think of recursion or dynamic programming.

The k-th term of the above series is: 2 k T(n/2 k) + kcn. Put 2 k = n, we have k = log 2 n. We put this value of k in the equation above to get: T(n) = nT(1) + cnlog 2 n. Here, T(1) and c are constants. So, we can write T(n) = An + Bnlog 2 n. Since the term nlog 2 n is larger than n, we can see that nlog 2 n is the dominant term.

Rank has several different meanings. In general, the concept of rank is used to treat an orthogonal array in terms of its subarrays. For example, a two-dimensional array may be dealt with at rank 2 as the entire matrix, or at rank 1 to work with its implicit one-dimensional columns or rows, or at rank 0 to work at the level of its individual atoms. Subarray with sum. Given an unsorted array of nonnegative integers, find a continous subarray which adds to a given number.
