Edit Sum2002 Midterm Review: String to Hex here.



stringToHex: numberString

	"takes in a string of numbers separated by spaces, and

	 returns an ordered collection of their hexadecimal

	 equivalents (each number gets converted to a separate

	 string)."



	| integerCollection hexCollection |



	integerCollection _ numberString findTokens: ' ' .

	hexCollection _ OrderedCollection new .



	(1 to: integerCollection size)

		do: [ :index |

			hexCollection add: (integerCollection at: index) asNumber hex .

		] .



	^ hexCollection .



this is good, but you can do it in one line, without temporary variables. how? Shaggz



stringToHex: numberString

	"smalltalk h4X0r"

	^ (numberString findTokens: ' ') collect: [ :element | element asNumber hex ] .
