Sort Names by First Name

Names are stored in the pattern last name first pattern [lastName, firstName].

For example given the name “Sharma, Rakesh”, “Rakesh” is first name and “Sharma” is last name.

Complete the method provided to return the collection of strings sorted based on their first name.

Method:

public static String[ ] SortByFirstName(string[ ] names)
{ 
   // code here 
}

Sample Input & Output: 

UTC	Sample Input	Sample Output
01	“Sharma, Rakesh”, “Patil, Parthiv”, “Gowda, Anil”, “Prasad, Vishnu”, “Khan, Amir”	“Khan, Amir”, “Gowda, Anil”, “Patil, Parthiv”, “Sharma, Rakesh”, “Prasad, Vishnu”
02	“Krishna, Gopal”, “Page, Larry”, “King, Gavin”, “Swamy, Krishna”	“King, Gavin” , “Krishna, Gopal”, “Swamy, Krish-na”, “Page, Larry”

Triplets

Triplets are a set of three similar things.

Complete the function to print all the triplets such that A+B = C 

public static void PrintTriplets(int[ ] data) 
{ 
    //write code here
}

Input & Output

UTC	Sample Input	Sample Output
01	data = {2,3,4,5,7}	<2,3,5> <2,5,7> <3,4,7>
02	array = {1,2,3,4,5,7,9}	<1,2,3> <1,3,4> <1,4,5> <2,3,5> <2,5,7> <3,4,7> <4,5,9>

Sum of consecutive elements in a subsequence

Complete the method to find the minimal length of the sub sequence of consecutive elements of the sequence, sum of which is greater or equal to the specified number.

Example:

5

1

3

5

10

7

4

9

2

8

If the specified number is 15 in the sequence
5 + 1 + 3 + 5 + 10 > 15 (length is 5)
1+3+5+10 >= 15 (length is 4)
3+5+10 >= 15 (length is 3)
5 + 10 >= 15 (length is 2)
10 + 7 >=15(length is 2)
There is no element in the array whose value is >= 15 and hence the minimal length is 2

public static int FindMinimalLength(int[] array, int value)
{
        //write code here
}

UTC	Sample Input	Sample Output
01	array = {5,1,3,5,10,7,4,9,2,8} value = 15	2
02	array = {1,2,3,4,5} value = 11	3
