value: the integer to be converted to string representation.
string: points to the buffer that is to hold resulting string.
radix: is the base of the number; must be in the range 2 - 36.
Write a function to remove duplicate entries from a sorted array.
Write a C function to test whether a number is a power of 2. Try to do it without using any loops.
