If the efficiency of the algorithm doIt can be expressed as O(n) = n², calculate the efficiency of the following program segment:

Given that the efficiency of an algorithm is 5n², if a step in this algorithm takes 1 nanosecond (10–9 seconds), how long does it take the algorithm to process an input of size 1000?
