WebThe master method is a formula for solving recurrence relations of the form: T (n) = aT (n/b) + f (n), where, n = size of input a = number of subproblems in the recursion n/b = size of each subproblem. All subproblems are assumed to have the same size. f (n) = cost of the work done outside the recursive call, which includes the cost of dividing ...
