Find all symmetric pairs in an array
WebYou are given a table, Functions, containing two columns: X and Y. Two pairs (X 1, Y 1) and (X 2, Y 2) are said to be symmetric pairs if X 1 = Y 2 and X 2 = Y 1.. Write a query to output all such symmetric pairs in ascending order by the value of X.List the rows such that X 1 ≤ Y 1.. Sample Input.

WebA Simple Solution is to go through every pair, and check every other pair for symmetric. This solution requires O (n2) time. A Better Solution is to use sorting. Sort all pairs by first element. For every pair, do binary search for second element in the given array, i.e., check if second element of this pair exists as first element in array.
WebOct 31, 2012 · Such pairs are called number of inversions in an array. It is one measure of how close the array is to being sorted. You can modify merge sort to efficiently count the number of inversions in O(nlogn) time. Refer to this for details.
