This code snippet solves the following condition:
NumberOfOnes(n) = n
It includes the function number_of_ones(n) that returns the number of ones found from the number 1 to n.
For instance:
number_of_ones(0) = 0 number_of_ones(1) = 1 number_of_ones(2) = 1 number_of_ones(10) = 2 number_of_ones(11) = 4 number_of_ones(12) = 5 ...
$ perl number_of_ones.pl [num]
Find the first occurence of NumberOfOnes(n) = n starting at "num"
