Returns indices of two numbers in an array that sum to a target
To use this class, just use TwoSum.twoSum(array, target) inside the main class
public int[] twoSum(int[] array, int target) {
//returns the result in an array form
}Example code, for understanding:
public static void main(String[] args) {
TwoSum twoSum = new TwoSum();
int[] result = twoSum.twoSum(new int[]{2,7,11,15}, 90);
System.out.println(result);
}
