Tip 2: Also look at the advantages of various job scheduling algorithm as there can be many theoretical MCQs

Debug the code and find the output.

Ans - 5 3
The above code swaps 2 numbers.

Debug the code and find the output.

Ans - 3
This is an example of accessing an array element through pointer notation. So *(a + i) is equivalent to a[i], and we are adding all the even indices elements, and subtracting all the elements at odd indices, which gives a result of 3.

class Employee{ 
float salary=40000; 
} 
class Programmer extends Employee{ 
int bonus=10000; 
public static void main(String args[]){ 
Programmer p=new Programmer(); 
System.out.println("Programmer salary is:"+p.salary); 
System.out.println("Bonus of Programmer is:"+p.bonus); 
} 
} 

Output :

Programmer salary is: 40000.0
Bonus of programmer is: 10000

Declare a character stack.
Now traverse the string exp. 
If the current character is a starting bracket ( ‘(‘ or ‘{‘ or ‘[‘ ) then push it to stack.
If the current character is a closing bracket ( ‘)’ or ‘}’ or ‘]’ ) then pop from stack and if the popped character is the matching starting bracket then fine.
Else brackets are Not Balanced.
After complete traversal, if there is some starting bracket left in stack then Not balanced, else Balanced.
