The first 2 are ultra-cool, no problems at all.
- The fun starts with the third one:
- Those thirteen questions are completely based on your problem solving capacity:
- There are questions based on data-structures like
- height of a tree,
- finding second largest number in an array
- questions using finite automata
- write a pgm to find whether a m/c is little endian or big endian
- Lot of questions were on bit-wise manipulation
- The 4th test on C/Java(i took C): is almost the same as the third one with questions like
- print a number in hexadecimal format without using sprintf
- Optimise the computations in the recursive “nth fibonacci number” algo without using iteration(fairly simple)
- Instead of using return(fib(n-2)+fib(n-1)), use init lofib=0,hifib=1, start with n=2,lofib=hifib;hifib=fib;fib=lofib+hifib
- Given any number say 12, find the next multiple of 8 eg 16 using bit-wise manipulations.
- Exchange the integers in a matrix across the secondary diagonal(or non-major diagonal)
- I tried hard but couldn’t get a common formula for all cases.
- And many more. No data structures book can directly help.
- One should have very good capacity to solve problems in a very efficient manners.
- One drawback about the test is that it is very lengthy.
- They could have kept some qs for the interview.
