Question

A function to find the H.C.F and L.C.M of two numbers is defined below: 

public void hcflcm(int n1, int n2)
{
   num = .....?1?.....
   while(n1 != n2)
   {
      if (n1 > n2)
      n1 = ........?2?........ 
   elseif(......?3?......)
      n2 = n2 - n1;
   }
   hcf = n1;
   1cm = .......?4....... / hcf;
}

In the above function, there are some places left blank marked with ?1 ?, ?2?, ?3? and ?4? to be filled with conditions / expressions.

Based on the above discussion, answer the following questions:

1. What condition/expression will be filled in place of ?1?
   1. n1 + n2
   2. n1 / n2
   3. n1 * n2
   4. n1 % n2
2. What condition/expression will be filled in place of ?2?
   1. n1 − n2
   2. n1 + n2
   3. n1 * n2
   4. None
3. What condition/expression will be filled in place of ?3?
   1. n1 == n2
   2. n1 >= n2
   3. n1 < n2
   4. n1 <= n2
4. What condition/expression will be filled in place of ?4?
   1. num
   2. n2
   3. n1
   4. n1 + n2

Answer 1

1. iii. n1 * n2
2. i. n1 − n2
3. iii. n1 < n2
4. i. num
