CampusPreparation and Learn coding for software professional

A very happy new year to all dear student. We will start this 2026 with functional programming and python programming language. So stay curious. Thank you all and love you all

Variable hoisting in javascript

With var declaration it doesn’t effect compiler where it is defined. We can use it before declaration also but with let and const it will give error.

// JAVA Code for Find Second largest
// element in an array
class SecondLargest{

/* Function to print the second largest
elements */
public static void print2largest(int arr[],
int arr_size)
{
int i, first, second;

/* There should be atleast two elements */
if (arr_size < 2) {
System.out.print(" Invalid Input ");
return;
}

first = second = Integer.MIN_VALUE;
for (i = 0; i < arr_size; i++) {
/* If current element is greater than
first then update both first and second */
if (arr[i] > first) {
second = first;
first = arr[i];
}

/* If arr[i] is in between first and
second then update second */
else if (arr[i] > second && arr[i] != first)
second = arr[i];
}

if (second == Integer.MIN_VALUE)
System.out.print("There is no second largest"
+ " element\n");
else
System.out.print("The second largest element"
+ " is " + second);
}

/* Driver program to test above function */
public static void main(String[] args)
{
int arr[] = { 12, 35, 1, 10, 34, 1 };
int n = arr.length;
print2largest(arr, n);
}
}
