Task 1 — Log Signal Decoder
Core Track10 levelssolve locallysubmit final number
Levels unlock sequentially. Reveal the official input per level, solve in Java, submit your final answer.

Each line contains random characters plus digits. Extract the first and last digit per line, combine into a two-digit number, then sum across all lines. If a line contains only one digit, treat it as both first and last (e.g. x7y → 77).
[example]
a1b2c -> 12 xxx9yyy -> 99 abc3def -> 33 sum = 144
