Microsoft interview Questions asked for a electrical engineering student

1. Given a rectangular (cuboidal for the puritans) cake with a rectangular piece removed (any size or orientation), how would you cut the remainder of the cake into two equal halves with one straight cut of a knife ?

2. You're given an array containing both positive and negative integers and required to find the sub-array with the largest sum (O(N) a la KBL).
Write a routine in C for the above.

3. Given an array of size N in which every number is between 1 and N, determine if there are any duplicates in it. You are allowed to destroy the array if you like.

4. Write a routine to draw a circle (x ** 2 + y ** 2 = r ** 2) without making use of any floating point computations at all.

5. Given only putchar (no sprintf, itoa, etc.) write a routine putlon the prints out an unsigned long in decimal.

6. Give a one-line C expression to test whether a number is a power of 2. [No loops allowed - it's a simple test.

7. Given an array of characters which form a sentence of words, give an efficient algorithm to reverse the order of the words (no characters) in it.

8. How many points are there on the globe where by walking one mile south, one mile east and one mile north you reach the place where you started.

9. Give a very good method to count the number of ones in a 32 bit number. (caution: looping through testing each bit is not a solution)

10. What are the different ways to say, the value of x can be either a 0 or a 1. Apparently the if then else solution has a jump when written

out in assembly.
if (x == 0)
y=0
else
y =x
