Some memory based questions:

  1. How many Prime numbers are there in universe?
  2. How will you prove that there are infinite prime numbers?
  3. You have given an empty stack which can hold atmost $3$ elements, what will be the top of stack after following operations: Push $6,$ Push $4,$ Push $1,$ Push $5,$ Pop, Pop
  4. n=10
    Fun(n)
    { 
        while(n>0)
        { 
            printf(n);
            Fun(n-1); 
        }
    }
    
  5. How many maximum regions will be there when we draw $19$ lines on the plane?

  6. You have a binary tree with $n_{1}$ vertices of degree $1, n_{2}$ vertices of degree $2, n_{3}$ vertices of degree $3.$ Explain $n_{3}$ in terms of $n_{1}$ or $n_{2}.$

  7. do {
    sum=0,i=0;
    i++;
    sum+=i;
    }
    while(i<5)
    printf(sum);
