Question

its one question broken into two parts

Consider the following code fragment. Compute the worst-case time complexity in
terms of n.
for (i=0; i<=n-1; i++){
for (j=i+1; j<=n-1; j++){
body of loop
}
}
For each pair (f, g) of functions below, state whether either, neither, or both of the
following are true: f(n) = 0(g(n)), g(n)
O(f(n)). Briefly justify your answers.
a. f(n) = In(n), g(n) = lg(n).
Note that In denotes log to the base e and lg denotes log to the base 2.
b. f(n) = 3", g(n) = n100
c. f(n) = 3", g(n) = 2"
d. f(n) = 1000n² + 2000n + 4000, g(n)
= 3n3 + 1
