In order to print all the nouns and verbs present in a given book, what is the underlying algorithm you see to achieve this problem? Discuss the pros and cons of your choice and also how would you test this method. You may assume that the system already knows what are nouns and verbs.

In a given array a = {1, 7, 3, 4, 5, 6, 2} Print the indices of all the combinations which lead to a given sum called target. For e.g. if the method is
Void PrintAllSumCombos(int[] arr, int target) - and the array shown above is passed with sum target = 7, then the output should be:

0, 3, 6
0, 5
1
2, 3
4, 6

Note: For simplicity, You may assume the array does not contain any negative numbers and also consider same set of indices with a different order as identical - for e.g. if 2, 3 is already printed, ignore 3, 2 as they are one and the same.

what will be the output of the following program and why...

#include<conio.h>
#include<stdio.h>

void main()
{
int a=10,b=20,diff;
diff=&a-&b;
printf("Difference=%d",diff);
float a1=10.0,b1=20.0;
diff=&a1-&b1;
printf("\nDifference=%d",diff);
char a2='a',b2='z';
diff=&a2-&b2;
printf("\nDifference=%d",diff);
double a3=10.0,b3=20.0;
diff=&a3-&b3;
printf("\nDifference=%d",diff);
getch();
}

Phonebook contains number and name.
1.use the java collection to add these entry (name and string).
2.Search the name by number
3.Remove the entry (name and string ) by using name.

I need to do this in Java...But if you can suggest me some Collection that can be used here, I shall do that....

I thought of :
1.using Hashmap,but here both name and number will be key....which wont be good...
2.Another option is to wrap both phone and number in an object and then add them to the list.And then Iterating and adding to the list.

Any other suggestions..?

Sally wants to create a dating website and decides to write an algorithm that takes a list of male and female users' preferences and returns the best matching of males with females. To test her algorithm, she manually calculates the best match. She then runs the algorithm and checks to see if the observed output matches with her manual calculation. What FIRST principle is clearly not being followed?



Fast

Independent

Repeatable

Self-checking

Timely

High coverage can always be achieved by writing a unit test for every method.

What is the difference between template class and class template ???

You are given n numbers x1,x2,x3,...,x(n-1) and x(n) and you can only do addition and subtraction operation with numbers, in how many ways can we get x1 S x2 S x3 S ..S x(n-1) = x(n) where S is from set +-
example X = {1,2,3,4,5,1}
possible solution 1+2-3-4+5
1-2+3+4-5

Which data structure will you use for implementing the dictionary. If hashing, list the hashing function you would probably use. If not,mention some other data structure !!!

what is the o/p of following along with justifying logic ?

{    
  int i=0;
  prrintf("%%%%");
}
