(Copy of Problem 47)
Benford's Law states that the distribution of leading digits is not random. This is probably because many things grow logarithmically. Extract the leading digit from these vectors.
10 --> 1
13 --> 1
0.3 --> 3
-4 --> 4
-5 --> 5
-0.006 --> 6
Input will be a vector
x = [1 0.3 -2 0.001 -0.0006, 582398, 3020];
Output should be
y = [1 3 2 1 6 5 3];
Avoid using for/while loops.
