Question

Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the element. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}.

import java.util.Scanner;
public class StudentScores {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int SCORES_SIZE = 4;
int[] lowerScores = new int[SCORES_SIZE];
int i;

for (i = 0; i < lowerScores.length; ++i) {
lowerScores[i] = scnr.nextInt();
}

/* Your solution goes here */

for (i = 0; i < lowerScores.length; ++i) {
System.out.print(lowerScores[i] + " ");
}
System.out.println();
}
}
