Just print "PPCGSC".

No assumptions! Never trust your brain too much, my dear friend.

There are no circles or $$$\pi$$$ in this problem D:

Each digit of the output corresponds to a number in the input.

Count the number of digits in the input numbers.

Print the number of digits of $$$a_1, \, a_2, \, a_3, \, \dots$$$ without spaces.

As mentioned in the problem statement, the length of the string s, denoted by |s|, is divisible by 3. This means we can treat every 3 characters as a group of some datatype

The answer is a string of characters. Each group of 3 bits can be interpreted as a character with an ASCII value from 0 to 255.

According to the problem, each robot is represented by a dot. So, after converting the original string into characters, certain characters in the resulting string visually resemble dots and can represent robots.

The time limit indicates how many characters you need to find or process.

After converting the original string s into a string of characters (by grouping every 3 bits or converting binary to ASCII), your goal is to identify the characters that visually resemble dots. These are:

! → ASCII code 33, has 1 dot

. → ASCII code 46, has 1 dot

: → ASCII code 58, has 2 dots

; → ASCII code 59, has 1 dot

? → ASCII code 63, has 1 dot

i → ASCII code 105, has 1 dot

j → ASCII code 106, has 1 dot

So, for each character in the converted string, check if its ASCII value matches any of the values listed above. If it does, add its corresponding value to your final answer.

The phrase "no modern system could immediately decode" suggests that even advanced AI systems, developed after thousands of years of evolution, would not be able to understand the string without interpreting it through specific rules.

Each input string is exactly 16 digits long. These digits can be interpreted as powers of two, and the final answer is composed of two distinct parts.

More specifically, the string should be split into 4-digit groups, and each group contributes to building the final output.

As shown in the test cases, the final result always consists of two components:

The first part is derived from the first group of digits and represents an instruction type.

The second part is the hexadecimal representation of the remaining three 4-digit segments.

The time limit gives a subtle hint about the maximum value the first 4-digit group (representing the instruction) can reach. In practice, this maps to a number from 0 to 6, indicating one of seven possible operations.

As suggested, the 16-digit string should be interpreted as four groups of four digits each. Here's how you process it:

Step 1 – Decode the Operation

Convert the first group (4 digits) into a decimal number.

This number maps to an instruction code:

0 → "AND"

1 → "ADD"

2 → "LDA"

3 → "STA"

4 → "BUN"

5 → "BSA"

6 → "ISZ"

Step 2 – Decode the Address

Take the remaining three groups (12 digits total).

Convert each 4-digit group to its decimal value, then to its 2-digit hexadecimal representation.

Concatenate the three hex values to form the memory address.

Final Answer Format

[Instruction] + [Hexadecimal Address]

High/Low, doesn't this mean sorting or smth so we get smaller ones or higher ones?

$$$b$$$ size is constant 5, and it is a prefix of the given medicines?

Now, for each prefix $$$b$$$, search for the medicine that starts with that prefix If the $$$a$$$ is low, then add the medicine that has the cheapest price; else if high, then add the most expensive medicine, and then at the end, print the total paid money

The digits of the number $$$n$$$ appear in a sorted order in the answer, don't they?

How does the number of zeros between each 2 digits change for each input? Does it even change?

How many zeros are there? Did you not think to count the zeros? xD

What is the sum of the digits that make the number $$$n$$$?

If the number $$$n$$$ has the digits $$$\texttt{ABCDE}$$$, add $$$(A + B + C + D + E)$$$ zeroes between each two consecutive digits after sorting the digits of the input so that there are a lot of them and the skeleton is happy!

What is the only thing that’s not loading in the problem? Search well, friend.

It’s the checker, but what are you asking for??

The output is just one single word.

Try printing "hint" and also check C's note.

By interacting with the checker in the first test case, you will found that the checker log answer differs according to the output, you’ll receive random answers till you type “hint” or “please”, in the “please” output, you’ll find a sentence with a missed word, according to the history of our skeleton, he is lonely, making the suitable word is $$$alone$$$.

The name of the problem refers to the idea of the game used in the problem, “Wordle”!

Check the memory limit in the problem; it helps a lot.

The problem idea is a simulation to the game “Wordle” (check Wordle) for more info.), the $$$GREEN$$$ refers to a right letter in right place, the $$$YELLOW$$$ refers to a right letter in wrong place, the $$$GREY$$$ refers to a wrong letter. Now comes the weird memory limit, 447 mb, for detecting the right word. If you google the answer to Wordle day 447, you’ll find the right word. I’ll let you google it; have fun :)
