In this article will be about GE Round 2: Online Code Writing Test questions and GE placement pattern.

I had shared my GE experience in my last post i.e. GE Placement Pattern - MY Review.
I have received good feedback.
Please do comment and ask any queries you have.

Today, i am gonna write about the GE Round 2: i.e. Code writing problem.

If u have cleared the GE aptitude test,you will receive an Email from GE (within 10-15 days).
Email will be containing 3 attachments having one problem in each attachment.

Problem No. 1
Express a given number as a summation of 4 positive primes.
Time limit of execution is 3.00 seconds.

Implement method/function which follows given signatures :

For Cpp:

void prime_sum(int n,int sol[ ]);

The input contains one integer number N (N<=100000). This number you will have to express as a summation of 4 primes and an array of interger where you have to store all 4 numbers.
If summation is not possible then just fill first 4 entries of array as -1.

For C Sharp :

public int[ ] prime_sum(int n);

The input contains one integer number N (N<=100000). This number you will have to express as a summation of 4 primes.

Your method should return an array containing 4 prime no.
If given no can not be expressed in expected form then it should return null value.

Sample Input :



Sample Output:

7 11 3 7

7 11 17 7

Problem No. 2
Adding two numbers:

"Write a function/class to add two integers."

You have to design only function/method to accept two integers and return back their sum. Your function must follow following

For C ++ :

int addno(int ,int);

For C Sharp :

public int addno(int,int);

2. Solving The problem :

For above example :

For C++ :

just enter ,

int addno(int a,int b)
return (a+b);

For C Sharp :

just enter :

public int addno(int a,int b)
return (a+b);

What NOT to enter :

* Header files
* Include statement
* Printing statement
* Anything that will generate Exceptions .

Basically anything But the above structure should not be entered in that area.

Problem No. 3

Expression Evaluation

Consider a pseudo code which takes following expression as input and produces given outputs.

Input Output

[ 0 ] 0
[ 1 ] 1
[ 0, 1 ] 1
[ 1, 1 ] 2
[ 1, [ 1, 2 ] ] -2
[ 1, 2, [ 8 ] ] -5
[ 1, [ 2 ], [ 3 ] ] -4
[ 9, [ 3, 4, [ [ 2 ] ] ] ] 0

Design a function/methos to implement above pseudo code by following prototype as

For CPP :

int ExpressEval(char * expression);

For C Sharp :

public int ExpressEval(string expression);


Accept expression to be evaluated as a string.

Output :

Return result of evaluation as an integer.

For e.g

consider input string to be "[1, 2 , [5 , 3 ] ]"

then your function must return -5.

Just design above method do not implement entire program/class.
That's IT...
Read the mail and you will understand the steps to be followed.
