Why is recursive equation of following code $T(n)=T(n/2)+O(1)$, not $T(n)=8*T(n/2)+O(1)$? int x=0; int A(n) { if(n==1) return 1; else { X+=8A(n/2)+n^3; } return X; }
int x=0; int A(n) { statement //takes O(1) time if(n==1) return 1; else { $X+=8.A\left ( \frac{n}{2}\right )+n^3$; } return X; } What is the time complexity f the above code?
