you have a sequence where each number is a multiple of 2 or 5 (so: 2^i * 5^j). Given the beginning of the sequence as 1,2,4,5,8,10,16... and find a algorithm to calculate the next number in the sequence?
You are given n real numbers in an array. A number in the array is called a decimal dominant if it occurs more than n/10 times in the array. Give an O(n) time algorithm to determine if the given array has a decimal dominant.
