Query on hashing


A machine needs a minimum of 100 sec to sort 1000 names by quick sort.the minimum time needed to sort 100 names will be approximately…
a)50.2 sec
b)6.7 sec
c)72.7 sec
d)11.2 sec


See for min time you have to do nlognn operations so likewise calculate the minimum time needed to do 1 operation now calculate the number of operations needed to do for 100 names and multiply it.
The answer I got is 6.7 sec.
Remember it is log base2
