44.A rundown of n string, every one of length n, is arranged into lexicographic request
utilizing the consolidation sort calculation. The most pessimistic scenario running season of this calculation
is
A.O (n log n)
B.O (n2 log n)
C.O (n2 + log n)
D.O (n2)
ANS:B
Clarification:
The repeat tree for consolidate sort will have level Log(n). Furthermore, O(n^2) work will
be finished at each level of the repeat tree (Each level includes n examinations
furthermore, an examination takes O(n) time in most pessimistic scenario). So time intricacy of this
Blend Sort will be O (n^2 log n) .

The recursion articulation becomes: T(n) = T(n/4) + T(3n/4) + cn After settling the
above recursion, we get \theta(nLogn).
46. Consider the Quicksort calculation. Assume there is a methodology for viewing as a
turn component what parts the rundown into two sub-records every one of which contains at
least one-fifth of the components. Let T(n) be the number of examinations required

A.T(n) <= 2T(n/5) + n
B.T(n) <= T(n/5) + T(4n/5) + n
C.T(n) <= 2T(4n/5) + n
D.T(n) <= 2T(n/2) + n
ANS:B
Clarification:
For the situation where n/5 components are in one subset, T(n/5) correlations are required
for the principal subset with n/5 components, T(4n/5) is for the rest 4n/5 components,
furthermore, n is for tracking down the turn. On the off chance that there are more than n/5 components in a single set
then other set will have under 4n/5 components and time intricacy will be
not exactly T(n/5) + T(4n/5) + n since recursion tree will be more adjusted
