To find the length of the variable \( a \), which consists of the characters \( \{ф, ы, в, а, л, д, п, р, о, ж, и\} \):

1. Count the number of individual elements (characters) in \( a \).

The string \( a \) contains 10 characters:

• ф
• ы
• в
• а
• л
• д
• п
• р
• о
• ж
• и

So, \( p = \text{length}(a) = 11 \).

Next, you mentioned \( b \) and \( d \) but did not specify what you need to do with them. If you want to compute their lengths as well:

• String \( b = \{м, и, р, о, п, р, о, ж, и, в, а, н, и, е\} \) has 14 characters.
• String \( d = \{б, и, о\} \) has 3 characters.

If there's anything specific you need to compute or another operation you want to perform, please let me know!
