In a sorted array the smallest difference is guaranteed to be between two consecutive elements, that's why I've thought of sorting. Minimum Difference in an Array - Arrays - Tutorial - takeuforward Problem statement:-Program to Minimum difference between two elements in an array. Write a program in C to find the maximum difference between any two elements such that the larger element appears after the smaller number. There is no requirement to combine two arrays, as you can obtain the difference by subtracting one element from the total sum. O(nlogm): for each element in A, use Binary Search method to find the element with the closest value in array B. The high-level idea is to apply Mo's trick to a data structure with the following operations. For example, Input: arr = { 1, 3, 5, 4, 8, 2, 4, 3, 6, 5 } x = 3, y = 2 Output: 2 Explanation: Element 3 is present at index 1 and 7, and element 2 is present at index 5.

If there is a set S with n elements, then if we assume Subset1 has m elements, Subset2 must have n-m elements and the value of abs (sum (Subset1) - sum (Subset2)) should be minimum. Yup.. Minimum difference pair | Practice | GeeksforGeeks But I still think what I'm saying makes sense; you don't have to sort the entire collection but you still need to do an O(n) operation. Sorted by: 8. 3. Looking more closely, we see the next quality is that the best candidate swap has the largest overlap with the first pair. Traverse through the array and create a hash array to store the frequency of the array elements. To partition nums, put each element of nums into one of the two arrays. To learn more, see our tips on writing great answers. Return the maximum difference. "Fleischessende" in German news - Meat-eating people? @jrook Updated the answer to give an explanation. If so, what if you just pre-computed the differences from one number to the next? See your article appearing on the GeeksforGeeks main page and help other Geeks. English abbreviation : they're or they're not. The actual implementation of pairwise() is probably more efficient in terms of space because it doesn't need to create 2 (shallow) copies of the list. List all pairs with difference equal to 1 in ascending order. Here the difference is minimum between 4 and 1 and so answer is 3. Expected Time Compelxity: O (N* log (N)) where N is length of array. Thanks for contributing an answer to Stack Overflow! Can consciousness simply be a brute fact connected to some physical processes that dont need explanation? "Fleischessende" in German news - Meat-eating people? What is the best algorithm for overriding GetHashCode? EDIT #2: My answer determines the smallest difference between any two adjacent values in a sequence, not the smallest difference between any two values in the sequence. I'm just curious, but can we do without sorting !! The minimum difference will be one of the differences from among the consecutive pairs in sorted order. Examples : English abbreviation : they're or they're not. For example, if , the minimal absolute difference is between and , so our algorithm should output the pair . Okay.. Calculate distance between two latitude-longitude points? The problem is that I'll have a lot of intervals to check I have to keep the original array intact. What is the complexity? Line-breaking equations in a tabular environment. Connect and share knowledge within a single location that is structured and easy to search. Given two sorted arrays, A and B, find i,j for which |A[i] - B[j]| is minimum. Count of elements which are not at the correct position, Rearrange an array to minimize sum of product of consecutive pair elements, Find the maximum cost of an array of pairs choosing at most K pairs, Find all indices of a given element in sorted form of given Array, Find the closest pair from two sorted arrays, Maximum length prefix of one string that occurs as subsequence in another. The frequency was calculated to check whether some element has frequency > 1 which means the absolute distance will be 0 i.e. Lets say sum of elements of set 1 is x than sum of elements of set 2 will be sm-x (sm is sum of all elements of arr). Given an array arr[] of N integers, the task is to find the maximum difference between any two elements of the array. Look at the following code that I wrote. It should be n^2, no ? In Python 3 this problem can be simplified by using the module itertools which gives the combinations available for a list. I know how to solved the problem in O(n^2) (brute force), but struggling to figure out a more efficient way.

Now for each query I loop through the whole array and look if b[j] is between L and R if it is compare its absolute difference to the first next element that is also between L and R keep the minimum and then do the same for that element until you get to the end. We can see that improvement happens when the pair we are swapping with has an opposite ordering (e.g., if a1 < b1 then a2 > b2 and vice versa). My job is to find the minimum difference between any two elements in the array. Approach 1 Use two loops, one loop finds any one of the elements and the second loop finds the other element in the same way. Is it better to use swiss pass or rent a car?
