Hello @mayankA47,

Master Method is a way to directly get the solution of a recurrence equation.
The master method works only for following type of recurrences or for recurrences that can be transformed to following type of equation:

T(n) = aT(n/b) + f(n) where a >= 1 and b > 1

Once, you have the above recurrence equation, the any of the following three cases can be used to find the solution:

  1. If f(n) = Θ(n^c) where c < Logba then T(n) = Θ(nLogba)

  2. If f(n) = Θ(n^c) where c = Logba then T(n) = Θ(ncLog n)

3.If f(n) = Θ(n^c) where c > Logba then T(n) = Θ(f(n))

check the value of f(n), and use the corresponding case from three mentioned above.

Hope, this would help.
Give a like, if you are satisfied.
