<prompt> Theha polelo e tloaelehileng ho tsamaisana le nomoro efe kapa efe ea linomoro tse tharo.nan  <response>: Instruction in English: Construct a regular expression to match any single three-digit number. . Response in English: To match any single three-digit number using a regular expression, you can use the pattern rbd3b.- b indicates a word boundary, so this ensures the three-digit number is a standalone number and not part of a longer sequence of digits.- d matches any digit 0-9.- 3 indicates that we want to match exactly 3 digits.- The r in front of the pattern indicates that it is a raw string literal, which makes it easier to include special characters like backslashes. .
