Quick sort is better but we group the words and then used

Answer / rob
They're looking for unique words, so just sorting isn't good enough. Quicksort can still have a worst case runtime of n^2, or 10 million squared operations. We should use mergesort to guarantee O(nlogn) runtime, and then have a for loop to go through the list comparing element[i] with element [i+1], omitting element[i] if it is equal to element [i+1], and otherwise storing it in a new array or printing it to the screen, an O(n) operation. Then the final runtime is O(nlogn + n), ignoring the constant time to insert elements into a new array.

Answer / swati
Merge sort or Heap sort ..b'coz these sorting has optimal
running time i.e O(nlogn)..

Write a program using one dimensional array that accept five values from the keyboard. Then it should also accept a number to search. This number is to be searched if it among the five input values. If it is found, display the message “Search number is found!” otherwise, display “Search is lost”. Example: Enter 5 numbers: 10 15 20 7 8 Enter number to search: 7 Search number is found!
