What is the shorthand formula for 52 playing cards?

The formula is as follows: Usually, there are 52 playing cards (excluding King of Size) used for memory games, including 40 number cards and 12 character cards. Poker looks very abstract. We usually convert each card into a set of numbers, and then we can record poker as numbers.

40 digital cards, the corresponding digital scheme is:

Spades stand for ten digits of 1 (the lower part of spades is like "1").

The heart represents the decimal digit of 2 (the upper part of the heart is two and a half arcs).

Grass flower stands for 3 of ten digits (grass flower consists of three semicircles).

A square represents a ten-digit 4 (a square has four sharp corners).

For example, spades 1 stands for 1 1 and spades 2 stands for12; Red heart 1 stands for 2 1, red heart 2 stands for 22, grass flower 3 stands for 33, box 4 stands for 44, and so on.

For cards with the number 10, it can be regarded as 0, that is, spades 10 stands for 10, hearts 10 stands for 20, flowers 10 stands for 30 and diamonds 10 stands for 40.

According to the above scheme, the digital codes required by the digital card include 10-49 * * * 40 codes.

Next are four kinds of character cards. It is suggested that J, Q and K respectively represent 5, 6 and 7 of ten digits, while spades, hearts, flowers and squares respectively represent 1, 2, 3 and 4 of single digits. Then, the number of spades J is 5 1, the number of hearts Q is 62, the number of flowers K is 73, the number of diamonds K is 74, and so on.
