Exercise 1.7
Patterns, like the ones below, are available in most drawing programs for filling regions. A
pattern is defined by an 8 x 8 array of bits. In each of the following two examples, the 8 x 8
array of bits on the left corresponds to the pattern on the right.

The Os represent white, and the 1s represent black. Each row is an 8-bit binary number. As we
know, a 4-bit binary number can be expressed as a single hex-digit, so an 8-bit binary number
can be expressed with two hex-digits. Designers specify a pattern by giving eight 2-hex-digit
numbers, one 2-hex-digit number per row. The two patterns given above are encoded as "11,
11, 11, 11, 11, 1, 11, 11" and "33, 33, СС, СС, 33, 3з, С, СС."
a. For each of the following patterns, give the eight 2-hex-digit encoding.
