I know this problem is similar to count number of subarrays with k different integers. Furthermore,two subarrays are distinct if they have atleast one different element. For example if input is [3,2,3,4] then output will contain [3],[2],[4],[3,2],[2,3],[3,4],[2,3,4].

However on execution and introspection,I found the result was always 0 for all test cases. This is because the variables on which the result depends always stays the same after every iteration. Say at iteration 1 the two pointers are 1 and 1 Then at iteration 2 the two pointers are 2 and 2 and so on I have listed my code.

We need to find the minimum range in array [l, r] both l and r are inclusive such that there are exactly k different numbers. A simple solution is to use two nested loops. The outer loop is used to pick a starting point and inner loop is used to pick an ending point. For every pair of starting-ending points, we count distinct elements in it and update result if the current window is smaller. We use hashing to count distinct elements in a range.

Optimization over above simple solution. The idea is to remove repetitions on left side after we find k distinct elements. Time complexity of this solution is O n. In every nested iteration, we either add an element or remove an element. Every element is inserted and removed at most once.

Python 3 program to find minimum range. Prints the minimum range that contains. Consider every element as. Find the smallest window starting.

There are less than k distinct. If there was no window with k distinct.The maximum subsequence sum is comprised of element indices and the sum is.

Call this value code ' '. First, we can easily to implement a sliding window to get a result of the number of different integers in that subarray is equal to or smaller than K.

## Subarray With K Distinct Integers

For example, [1,2,3,1,2] has 3 different integers: 1, 2, and 3. Subarrays with K Different Integers. Given an array A of positive integers, call a contiguous, not necessarily distinct subarray of A good if the number of different integers in that subarray is exactly K. If is a rational number which is also an algebraic integer, then 2 Z. Return the number of good subarrays of A. Given an arr[] containing n integers and a positive integer k.

Given an array arr[] of N positive integers and an integer K, the task is to find the maximum distinct prime factors in a subarray of length K. Explanation for the above mentioned problem. If there isn't one, return 0 instead. Given a positive integer k, how large a group of people is needed to ensure that either there exists a subset of k people in the group. A set is any unordered collection of distinct objects.

Let d be a positive integer, and let S be the set of all positive integers. Count Numbers with Unique Digits Given an nonnegative integer array, find a subarray where the sum of numbers is k.

This video explains how to find a subarray from a given array having sum equals to a given sum value. We need to find the minimum range in array [l, r] both l and r are inclusive such that there are exactly k different numbers.

Write a program to find the maximum sum of a subarray of size K. Power of Four Easy Given an array arr[] of size N and an integer K. The task is to find the count of subarrays such that each subarray has exactly K distinct elements.

Approach: To directly count the subarrays with exactly K different integers is hard but to find the count of subarrays with at most K different integers is easy. So the idea is to find the count of subarrays with at most K different integers, let it be C Kand the count of subarrays with at most K — 1 different integers, let it be C K — 1 and finally take their difference, C K — C K — 1 which is the required answer.

Count of subarrays with at most K different elements can be easily calculated through the sliding window technique. The idea is to keep expanding the right boundary of the window till the count of distinct elements in the window is less than or equal to K and when the count of distinct elements inside the window becomes more than Kstart shrinking the window from the left till the count becomes less than or equal to K.
