what is the best algorithm to sort out unique words from a
list of more than 10 million words(1 crore+)?
we need the best technique in the terms of execution time.

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)..

Implement a command console for changing settings on a particular object. The command console should allow you to enter a string and will return the response (very similar to a terminal session). The commands are as follows: SET propertyname=newvalue will change the target object’s member named “propertyname” to have a value equal to “newvalue”. If the input value is incompatible (i.e. an int being set to a string), print out an appropriate error message. GET propertyname will print out the current value of the target object’s member named “propertyname”. GET * will print out a list of all target object members and their current values. The system should be extensible for future commands and should accept an arbitrary object, such that another developer could insert another object into the system and rely on the command console to get and set the properties correctly.

1. Write a program that performs the following. The user inputs a number and then enters a series of numbers from 1 to that number. Your program should determine which number (or numbers) is missing or duplicated in the series, if any. For example, if the user entered 5 as the initial number and then entered the following sequences, the results should be as shown. Input Sequence Output ---------------------- --------------- 1 2 3 4 5 Nothing bad However, if 7 were the high number, the user would see the results on the right for the following number entries: Input Sequence Output ---------------------- --------------- 1 3 2 4 5 Missing 6 Missing 7 And if 10 were the high number and the user entered the numbers shown on the left, note the list of missing and duplicate numbers: Input Sequence Output ---------------------- --------------- 1 2 4 7 4 4 5 10 8 2 6 Duplicate 2 ( 2 times) Missing 3 Duplicate 4 ( 3 times ) Missing 9

write a c program, using for loop, that accepts and odds two numbers. The output must be the sum and the addens. This should be repeated 5 times while the first number is decremented by one and the second number is incremented by 1.
