2.

1.when a user inputs values, if it is even perform a
divide by 2, else perform n*n-1 and store them in a
sequence.the output must be the largest power of 2 in
the given sequence.

2.write a prog to generate pythagorian triads of the

THE QUESTION IS:FIND THE NEXT PERMUTATION IN LEXICOGRAPHIC

NOTE: MAXIMUM QUESTIONS ARE FROM OLD QUESTION PAPERS

Interview Procedure

The interview is basically a technical inteview with stress on C again. Programs can be given on the spot such as reversal of a string implemented using data structures (like nodes) to test your knowledge and understanding of C concepts. Also questions on DBMS, OS and Data Structures can be asked.

The written test is of two parts:
Section A : Aptitude Test
Section B : C Test
The aptitude was a mixture of verbal, analytical and quantitative questions. It is based on a pattern similar to the GRE tests and questions found in R.S Agarwal
The c section tests your knowlege in pointers and basic C concepts.
