all about divide and conquer code example

Example 1: Divide and conquer algorithm

DAC(a, i, j)
{
    if(small(a, i, j))
      return(Solution(a, i, j))
    else 
      m = divide(a, i, j)               // f1(n)
      b = DAC(a, i, mid)                 // T(n/2)
      c = DAC(a, mid+1, j)            // T(n/2)
      d = combine(b, c)                 // f2(n)
   return(d)
}

Example 2: divide and conquer algorithm

divide and conquer: 
  split the problem into sub problems, 
  solve each sub problem to eventually solve the main problem
