**absolute****difference**is the positive**difference**between two values and , is written or and they are equal. If and , . Given an array of integers, find the minimum**absolute****difference**between any two elements in the array. Example. There are**pairs****of****numbers**: and . The**absolute****differences**for these**pairs**are , and . - Note: if you want to calculate the
**absolute difference**between times, you only can apply =ABS (A2-B2) and then format values .... "/>**Count number of pairs with absolute difference k** - Difficulty Level : MediumAsked in : Google, Facebook, Amazon Understanding the problem. Problem Description: Given an array of n integers and given a
**number****K**, determines whether there is a**pair****of**elements in the array that sums to exactly**K**. For example : Input : A[] = [-5, 1, -40, 20, 6, 8, 7 ], K=15 . Output: true ( 7, 8 and -5, 20 are the**pairs****with**sum 15) - Sep 19, 2021 ·
**Count****Number****of****Pairs****With****Absolute****Difference****K**via Hash Table We can**count**the**numbers**, and then use the multiplication rule to accumulate the answer quickly. The following algorithm takes O (N) time and O (N) space - based on a hash table..**Pairs****with**specific**difference**. - Method 5 (Use Sorting) : Sort the array arr. Take two pointers, l, and r, both pointing to 1st element. Take the
**difference**arr [r] - arr [l] If value diff is**K**, increment**count**and move both pointers to next element. if value diff >**k**, move l to next element. if value diff <**k**, move r to next element.
