Find Last Element

#1

import java.util.*;
public class Main {
public static int lastIndex(int a[], int n, int m)
{
if(n<=1)
return -1;
int ans;
if(a[n-1]==m)
return (n-1);
else
ans = lastIndex(a, n-1, m);
return ans;

}

public static void main(String[] args) {
	Scanner sc= new Scanner(System.in);
	int i,m;
//	System.out.println("Enter the length of array");
	int n= sc.nextInt();
	int a[] = new int[n];
	for(i=0; i<a.length; i++)
	{
		a[i] = sc.nextInt();
	}
//	System.out.println("Enter the target value");
    m = sc.nextInt();
    int ans = lastIndex(a,n,m);
    System.out.print(ans);

}

}
What is the test case 1? The output is the same but test case 1 is showing error.

Hi @Ashi,
Please remove the = in the first if statement … use (n<1) instead of (n<=1) and the code will run fine
