Q.

Consider the brute force implementation in which we find all the possible ways of multiplying the given set of n matrices. What is the time complexity of this implementation?

A. o(n!)
B. o(n3)
C. o(n2)
D. exponential
Answer» D. exponential
Explanation: the time complexity of finding all the possible ways of multiplying a set of n matrices is given by (n-1)th catalan number which is exponential.
