This paper is from IIIT, Hyderabad (October, 2003)

 

1. In how many different ways, a rectangle can be cut into 4 identical parts.  

2. Using the numbers 1, 2, 25, 50, 75, 100 Exactly one time, give an expression which will give the answer as 383.

3. Volume of sphere is (PI)*(Theta) Cubic-meters and Surface area is (PI)*(Epslon) Square-meters And both are digit integer numbers. What is the value of radius?

4. In the figure given below, Replace '?' mark by any operator (+, -, *, /, =) and if we leave as it is, numbers are considered together and forms either 2 or 3 digit numer. Generate an expression using some symbols.
   
             ------------------------
                | ? | 2 | ? | 3 |
            ------------------------
              | 2 | | ? |
             ------- ------
              | ? | | 1 |
            ------------------------
            | 6 | ? | 1 | ? |

5. Analise the Programe
     main()
       {
      int x=1,y=1;
      while( (x > 0) && (y > 0) )
         {
         printf("%16d%16d",x,y);
         x += y;
         y += x;
          }
        }

6. Start from a random number, generate a sequence such that if number is odd multiply it 3 and add  1. If number is even, divide the number by 2. This Sequence will always cyclic with 4, 2, 1. In this   sequesce, find the maximum power of 2 generaged in the sequence and print only the power, not   the sequence.
   

7. Start with a random 2 digit number, The series is generated by multiplying the number by 2 and placing the last 2 digits as the next number. Series continues until one of the element repeats. 

8. write a function maxsubstring(str,alpha,theta) str is the source string and have to return maximum sub string which  starts with alpha and ends with theta.

9. what will this line will do? if it is legal?   B -= (B < 0) * 2 * B;
   

10. what does this function do??
     int f(int p)
        {
       int i = 0, t = 1, s = 1;
       while( s <= p)                                                                                        
           {
              i++;
              t += 2;
             s += s;
           }
         return i;
        }
