String Lab

Cut the exact piece of text the job asks for, on a ruler that counts from one

Cut 1 / 7 Correct: 0 Score: 0

How to play: the ruler under the text is the index of every character, starting at 1. Pick the expression that produces exactly the target. All four are then run for real, so a call that is one character short shows you which character it missed.

Every candidate, actually run
