yes this explanation is correct
this is concept of permutation and combination
DP with Matrix Exponentiation Concept Doubt
Yeah, that’s the one way I understood the concept of m^n. I am sure, there are other ways to derive the concept of m^n but I don’t have any clue right now.
Bhaiya, can you kindly share your explanation, how you come up with m^n as a total number of possible arrays with m numbers…
And back to your solution using set theory, so if we take P,Q,R,S are four sets and make a venn diagram then, I think that
P U Q U R U S=m relation holds true.
And, if it’s true then it means that m is the universal set in the venn diagram.
So, is it correct?
