Big O Table

Table of Big O

This table is from CP3 and gives an idea of what complexity is necessary for different input sizes to achieve AC (all correct) without hitting TLE (time length exceeded). Reading the first line: if max N=11, an algorithm of factorial complexity or N^6 (or better) is acceptable.
