Histogram by the Hundreds

Write a program that reads a sequence of nonnegative integers and
reports the histogram by the hundreds: write out how many numbers were
between 0 and 99, how many between 100 and 199, how many between 200 and
299, and so on.

Input

The data sequence is to be provided completely in a single line, with
spaces separating the consecutive numbers.

Output

For each interval [N, M], where N is a multiple of 100 and M = N + 99,
such that some value in the input sequence belongs to the interval,
write a line reporting the interval (with its square brackets and its
comma and space), immediately followed by a colon and a space, and then
the quantity of numbers in the input falling within that interval. The
intervals must be ordered according to their left endpoint N.
