Mission Briefing

Attention, Coders! A rogue artificial intelligence known as G.L.I.T.C.H. has infiltrated our local network, blocking all outgoing data. To bypass the system lockdown, your team must navigate four secure mainframe chambers.

Each chamber contains an essential coding challenge. Solving a chamber reveals a 1-Character or 4-Digit Decryption Key. Record the keys on your Mainframe Decoder below. Once all four are solved, decode the Master Password to trigger a full system reboot!

The Path of Logic

Core Skill: Sequencing & Algorithms

STATUS: LOCKED

CHAMBER OBJECTIVE:

Computers execute instructions in a precise, top-to-bottom sequence. Follow the navigation algorithm step-by-step on the Server Grid below. Mark your path. The letter of the cell where you end up is your Chamber 1 Key.

Server Grid Matrix:

Y \ X	0	1	2	3	4
0	START	P	T		G
1	M	A		C	X
2	L		U	E	H
3	N	O	R		F
4	Y	K	Q	W	Z

The Echo Chamber

Core Skill: Loops & Repetition

STATUS: LOCKED

CHAMBER OBJECTIVE:

Loops are blocks of code that repeat a certain number of times to perform tasks efficiently. Evaluate the nested loops in the pseudocode box. Carefully trace the output string, and then extract the final key sequence!

PSEUDOCODE

SET Final_String = ""
FOR i FROM 1 TO 3 DO:
    APPEND "X" TO Final_String
    FOR j FROM 1 TO 2 DO:
        APPEND "Y" TO Final_String
    END FOR
    APPEND "Z" TO Final_String
END FOR

Step-by-Step Trace Ledger:

Complete the output string generated after each loop iteration (i) below:

When i = 1:

When i = 2:

When i = 3:

Final Compiled String:

1 2 3 4 5 6 7 8 9 10 11 12

CHAMBER 2 KEY DECRYPTOR:

Extract the letters from Compiled String indices 5, 8, and 12 to form your 3-character decryption key:

INDEX [5] =

INDEX [8] =

INDEX [12] =

Chamber 03

The Gatekeeper's IFs

Core Skill: Conditionals (If-Then statements)

STATUS: LOCKED

CHAMBER OBJECTIVE:

Conditionals allow a program to make decisions based on specific criteria. Determine the printed output of each segment given the active state of three network variables below. Put them together to form your 4-letter Chamber 3 Key.

Active Variables:

A = 15 B = 8 C = true

SEGMENT 1 IF-ELSE

IF A > 12 THEN
    PRINT "N"
ELSE
    PRINT "S"
END IF

Outputs letter:

SEGMENT 2 ELSE-IF

IF B < 4 THEN
    PRINT "I"
ELSE IF C == true THEN
    PRINT "O"
ELSE
    PRINT "A"
END IF

Outputs letter:

SEGMENT 3 COMPARING

IF A - B == 7 THEN
    PRINT "D"
ELSE
    PRINT "T"
END IF

Outputs letter:

SEGMENT 4 AND BOOLEAN

IF B > 6 AND C == false THEN
    PRINT "U"
ELSE
    PRINT "E"
END IF

Outputs letter:

CHAMBER 3 DECRYPTED MASTER STRING:

Place the segment letters in order (Segment 1 to 4) to verify the password:

The Bug Hunt

Core Skill: Debugging & Error Finding

STATUS: LOCKED

CHAMBER OBJECTIVE:

Debugging is the process of finding and fixing errors in code. There are **3 specific errors** in G.L.I.T.C.H.'s broken countdown script below. Identify the error type and match with its line number to decrypt the key!

Broken_Script.py

01:let counter = 10

02:let target = 0

03:while counter >= target:

04: counter = counter + 1 // Infinite loop bug!

05: print("T-minus " + counter)

06: if counter = 5: // Syntax bug! Needs '=='

07: print("Halfway there!")

08: target = "zero" // Type bug! Breaks condition

09:print("Reboot complete!")

Your Error Diagnosis Sheet:

1. LOGIC BUG

Causes infinite loops or unexpected runtime loop results.

Line:

2. SYNTAX BUG

Grammar violation like using `=` instead of `==` in conditionals.

Line:

3. TYPE BUG

Incorrect type switch (text vs numbers) causing a crash.

Line:

CHAMBER 4 KEY:

Sequence the error line numbers in ascending order to create the 3-digit override code:
