The value of pseudo code

Sometimes, you will need to understand the problem and write a pseudo code before you even start thinking about solving problems.

i.e To determine whether a year is a leap year, follow these steps:

       1. If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.
       2. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.
       3. If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.
       4. The year is a leap year (it has 366 days).
       5. The year is not a leap year (it has 365 days).

So, what is the pseudo code for this problem?
