Java Loop Control Flow

Background

Java labeled break and continue provide control over nested loops, useful for search and matrix traversal.

Problem

Write a Java method that finds the first pair of numbers in an array that sum to a target, using nested loops with labeled break.

Input

An array of integers and a target sum.

Output

An int array of the two indices, or null if no pair exists.

Sample tests

Input: [2, 7, 11, 15], target=9

Expected: [0, 1]
