## Solution in Java

``````import java.util.*;
public class codechef {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int[] item_number = {101,102,103,104};
String[] item_name = {"Milk", "Cheese", "Ghee", "Bread"};
int[] price = {42,50,500,40};
int[] stock = {10,20,15,16};

int item_num = sc.nextInt();
int quant = sc.nextInt();
int temp =0,flag=0;;
for(int i = 0; i<4 ;i++) {
if(item_num ==item_number[i]) {
temp = i;
flag=1;
}
}

if(flag== 0){
System.out.println("INVALID INPUT");
System.exit(0);
}
if(quant > stock[temp]) {
System.out.println("NO STOCK");
System.out.println(stock[temp]+" "+"LEFT");
}else if(quant <= stock[temp]){
System.out.println((float)(price[temp]*quant)+" "+"INR");
System.out.println(stock[temp]-quant+" "+"LEFT");
}
}
}
