Pairs Game C Program

Pairs Game C Program' title='Pairs Game C Program' />Count all distinct pairs with difference equal to k. Given an integer array and a positive integer k, count all distinct pairs with difference equal to k. Examples. Input arr 1, 5, 3, 4, 2, k 3. There are 2 pairs with difference 3, the pairs are 1, 4 and 5, 2. Input arr 8, 1. There are 5 pairs with difference 4, the pairs are 0, 4, 4, 8. Method 1 Simple A simple solution is to consider all pairs one by one and check difference between every pair. Following program implements the simple solution. We run two loops the outer loop picks the first element of pair, the inner loop looks for the other element. This solution doesnt work if there are duplicates in array as the requirement is to count only distinct pairs. The largest and most uptodate repository of Emacs packages.

With. Diff. Kint arr, int n, int k. Pick all elements one by one. See if there is a pair of this picked element. Driver program to test above function. Count of pairs with given diff is. Pairs. With. Diff. Karr, n, k. Count of pairs with given diff is 2. Time Complexity of On. Method 2 Use SortingWe can find the count in On. Fabriwin Download'>Fabriwin Download. Logn time using a On. Logn sorting algorithm like Merge Sort, Heap Sort, etc. Following are the detailed steps. Initialize count as 0. Sort all numbers in increasing order. Remove duplicates from array. Do following for each element arri. Binary Search for arri k in subarray from i1 to n 1. If arri k found, increment count. Return count. A sorting based program to count pairs with difference k. Standard binary search function. Searchint arr, int low, int high, int x. Searcharr, mid 1, high, x. Searcharr, low, mid 1, x. Returns count of pairs with difference k in arr of size n. Pairs. With. Diff. Kint arr, int n, int k. Sort array elements. Pick a first element point. Searcharr, i1, n 1, arri k 1. Count of pairs with given diff is 2. Time complexity The first step sorting takes On. Logn time. The second step runs binary search n times, so the time complexity of second step is also On. Logn. Therefore, overall time complexity is On. Www Hindi Serials Com Star Plus. Logn. The second step can be optimized to On, see this. Method 3 Use Self balancing BSTWe can also a self balancing BST like AVL tree or Red Black tree to solve this problem. Following is detailed algorithm. Initialize count as 0. Insert all elements of arr in an AVL tree. While inserting. ignore an element if already present in AVL tree. Do following for each element arri. Search for arri k in AVL tree, if found then increment count. Search for arri k in AVL tree, if found then increment count. Remove arri from AVL tree. Time complexity of above solution is also On. Logn as search and delete operations take OLogn time for a self balancing binary search tree. Method 4 Use HashingWe can also use hashing to achieve the average time complexity as On for many cases. Initialize count as 0. Insert all distinct elements of arr in a hash map. While inserting. ignore an element if already present in the hash map. Do following for each element arri. Look for arri k in the hash map, if found then increment count. Look for arri k in the hash map, if found then increment count. Remove arri from hash table. A very simple case where hashing works in On time is the case where range of values is very small. For example, in the following implementation, range of numbers is assumed to be 0 to 9. A simple hashing technique to use values as index can be used. An efficient program to count pairs with difference k when the range. MAX 1. 00. 00. 0. Pairs. With. Diff. Kint arr, int n, int k. Initialize count. Initialize empty hashmap. MAX false. Insert array elements to hashmap. MAX hashmapx k. Method 5 Use SortingSort the array arr. Take two pointers, l and r, both pointing to 1st element. Take the difference arrr arrlIf value diff is K, increment count and move both pointers to next elementif value diff k, move l to next elementif value diff lt k, move r to next elementreturn count. A sorting based program to count pairs with difference k. Returns count of pairs with difference k in arr of size n. Pairs. With. Diff. Kint arr, int n, int k. Sort array elements. Driver program to test above function. Count of pairs with given diff is. Pairs. With. Diff. Karr, n, k. Output Count of pairs with given diff is 2.
