import java.util.*;

}

public static void bubbleSort(int[] arr){
	for(int i = 0; i < arr.length; i++ ){
		for(int j = i + 1; j < arr.length - i; j++){
			if(arr[i] > arr[j]){
				int temp = arr[i];
				arr[i] = arr[j];
				arr[j] = temp;
			}
		}
	}
}

public static void targetSumPairs(int[] arr, int target){
	for(int i = 0; i < arr.length - 1; i++){
		for(int j = i + 1; j < arr.length; j++){
			if(arr[i] + arr[j] == 5){
					System.out.println(arr[i] + " and " + arr[j]);
			}
		}
	}
}

public static void takeInput(int[] arr){
	for(int i = 0; i < arr.length; i++){
		arr[i] = scn.nextInt();
	}
}

}

why my 2 test cases are failing ??
