Calculation of temporal complexity (entry divisible by 2)

How would I calculate the time complexity or T(n) of this section of code? j=1; while(j<=n/2){ i=1; while(i<=j){ cout<<j<<i; i++; } j++ } I think you can assume that n is divisible by 2.It's not hard to count the total number of iteratio

I'm really confused about the complexity of time

I understand that an algorithm's time T(n) can be bounded by O(g(n)) by the definition: T(n) is O(g(n)) iff there is a c > 0, n0 > 0, such that for all n >= n0: for every input of size n, A takes at most c * g(n) steps. T(n) is the time that is t

The program runs at a certain time
