I am going to cover few intrerview questions which I have faced recently as a part of my internal job search in my current organization.
Day 1(BU NAME: xxxx) :
On line written test (C, C++, Java) http://hackerrank.com/
Bascially you will get a link with question. we have to write the program and that will sumit remostly the code and compile and validate the code using various automated test cases.
Q 1) Try to find find in a given in put string it is complete it or not (ex for complete: {,(.[,......},],).
how to interpret the question: Intension is to find {} are presnt or () or [] ....
How to solve:
int type1=0;
Approach 1:
while(string != null)
{
swtich (char)
{
case '{':
case '}' :
{
if (char == '{')
{
type1++;
}
else
{
type1--;
}
}
...........................
}
if(type1 || type2 || type3 ||..)
{
not a perfect string
}
}
Approach 2:
Use a stack to store the value and search
Q 2 )given charcaters...like ...a, b, c, d etc...
need to print possible combinations: a, b,c,d, ab, ac,ad, bc,bd,ba, cd,ca,cb, abc, a....
How to interpret the question: Basically they want to have a loo and get hold on that...
Solution:
Q3) what is the minimum starting value need to reach the destination.
Each state in a game will give + or -ve. If we have -ve mean...we will die.
Logic: we should always >=0 most important at every step/state.
Q4) two friends are working....A done Mn days ...and B done Ndays work...
A do better than B.
how many days it take to complete the work "P))" days done by A .....with B.
1+ (p/A-B)
Q5) Find a given number is bouncy or not...
123456 , 45678 ...is correct number
34567 is boucy number
Logic: it is expected all digits should be in increase order....
Day 2(BU NAME: xxxx) :
1) What is abstrct class
2) private/public/protec data how it will be there in derived class..
3) what is virutcal function
4) pure vitural function...vptr
5) unix process memory layout
6) siganls
7) segmenation fault/segbus error.
8) what is late binding.
