#C11819. Find Pair with Given Difference
Find Pair with Given Difference
Find Pair with Given Difference
You are given a list of N integers and an integer k. Your task is to find two distinct indices i and j such that the absolute difference between arr[i] and arr[j] is exactly \(k\), i.e., \(|arr[i] - arr[j]| = k\).
If such a pair exists, output the indices in the order they are found separated by a space. Otherwise, print -1
. If multiple answers exist, any valid pair is acceptable.
Note: The indices are 0-based.
inputFormat
The first line contains two integers: N
(the number of elements in the array) and k
, separated by a space.
The second line contains N
integers separated by spaces.
outputFormat
If a pair of indices exists that satisfies the condition \(|arr[i] - arr[j]| = k\), print the two indices separated by a space. Otherwise, print -1
.
