Amazon Interview Question 1

10 000 integer numbers in an array, Each number is 10 bit. Sort the array

10 bit means there's only 2^10 = 1024 possible values. Use counting sort. Create an array of 1024 integers and in the i-th index keep the number of occurrences of the i-th possibility. IN the end, just traverse your occurrence count array printing each element the number of times that it occurs.
