Question

4. S={ all (strings) words that can be made from letters in A that are shorter than 6 letters}. Calculate the cardinality of S? 5. M={ all finite (strings) words that can be made from letters in A }. What is the cardinality of M? Justify. 6. Describe 1:1 correspondence between M and natural or integer numbers. 7. A = { letters in your first name} C={ letters in your first name in the inverse order} Consider matching A with C following the priorities: a letter in A loves the same letter in C a letter in C loves the letter in A which is listed in the same position ( i.e first in C love first in A). What matching respecting the priorities is the best for these two sets? What is the best 'happiness' score in this case?

          4. S={ all (strings) words that can be made from letters in A that are shorter than 6 letters}.
Calculate the cardinality of S?

5. M={ all finite (strings) words that can be made from letters in A }. What is the
cardinality of M? Justify.

6. Describe 1:1 correspondence between M and natural or integer numbers.

7. A = { letters in your first name}  C={ letters in your first name in the inverse order}

Consider matching A with C following the priorities:

a letter in A loves the same letter in C

a letter in C loves the letter in A which is listed in the same position ( i.e first in C love first in
A).

What matching respecting the priorities is the best for these two sets? What is the best
'happiness' score in this case?

5. M= all finite (strings) words that can be made from letters in A . What is the
cardinality of M? Justify.

6. Describe 1:1 correspondence between M and natural or integer numbers.
