Diameter of the treee

#1
  1. In tree problems the time complexity of the program depends upon the recursive call made by the algorithm??
  2. For computing the complexity the recursion tree is best to derive recurrence relation ??

  1. yes
  2. yes
    and also to help solve recurrence relations, you can also look for master theorem on the internet.
