Question
java
getDup accepts an array and returns an int.
If there is any element is duplicated, the method counts how many of those present in the array.
Example :
getDup(["1","2","aa"',"1"])
returns:2
("1" is duplicated and there are two "1"s so return is 2)
class Main {
public static int getDup(String[] r) {
}
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String [] strs = new String[in.nextInt()];
for(int i=0; i < strs.length; i++) {
strs[i] = in.next();
}
System.out.println(getDup(strs));
}
}
hint:
- you will need a nested array the will run on the array we get from the method argument.
- inside the nested loop you will need to check if the main array element is equal to the current
