Mar 21, 2021 · Two pairs (X1, Y1) and (X, Y) are said to be symmetric pairs if X1=Y2 and X2=Y1. Write a query to output all such symmetric pairs in ascending order by the value of X. List the rows such that X ≤ Y .
Mar 19, 2024 · Solution: Here we have two conditions to satisfy, Distinct values. Condition 1: X1=Y2 and X2=Y1. Condition 2: symmetric pair where X ≤Y. and then order by x values. select distinct f1.x, f1.y....
-- Two pairs (X1, Y1) and (X2, Y2) are said to be symmetric pairs if X1 = Y2 and X2 = Y1. -- Write a query to output all such symmetric pairs in ascending order by the value of X. -- List the rows such that X1 ≤ Y1.
Jul 7, 2023 · The Problem. Given a table, Functions, containing two columns: X and Y. Two pairs (X1, Y1) and (X2, Y2) are said to be symmetric pairs if X1 = Y2 and X2 = Y1. The task is to write a SQL query that outputs all such symmetric pairs in ascending order by the value of X, while ensuring X1 ≤ Y1.
Raw. You are given a table, Functions, containing two columns: X and Y. Two pairs (X1, Y1) and (X2, Y2) are said to be symmetric pairs if X1 = Y2 and X2 = Y1. Write a query to output all such symmetric pairs in ascending order by the value of X. List the rows such that X1 ≤ Y1.
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 .
Aug 13, 2023 · What are symmetric pairs in Hackerrank? Two pairs (a, b) and (c, d) are said to be symmetric if c is equal to b and a is equal to d. For example, (10, 20) and (20, 10) are symmetric.
Jul 9, 2023 · We can solve this problem by not comparing the pair with itself. Another solution is to use the count function to count the number of times each pair appears in the results. If the count is 1, then the pair is not a sy pair.
