Question
Using the operations corresponding to the gates in the gate table, derive a minimal (with respect to literals) expression for the number of days in a given month. The expression has five bits of input:

- \( m_3, m_2, m_1, m_0 \): a four-bit number indicating the month (0001 is January, 0010 is February, etc.)
- leap: a single bit that is true if and only if it is a leap year

The expression has five output bits:

- \( d_4, d_3, d_2, d_1, d_0 \): a five-bit number indicating the number of days in the given month. See Thirty Days Hath September for the rules.
