What is the time complexity for this?

Question

nlog2n+3n^2+4n^3+n+10

from this polynomial what we supposed to consider either O(n^3) or O(logn)

from log2n we can have log2+logn right so it is logn .like wise

what we have to consider please tell me?

Answer 1

实际上，它是O（m * n），除非您有错字，并且两个循环都应从0迭代到n，在这种情况下，它应该是O（n ^ 2）。
