tomgullo / convert_roman_to_dec.groovy

Created March 5, 2012 14:08

Groovy script to convert decimals to roman numerals

	/*
	The key is to map unique roman numerals to binary values, then start from traversing through the list from high values to low values.
	When binary is greater, start building the roman string, subtracting from the binary as you go.

	Takeaway: If writing a conversion problem, make list mapping one to another. Also, look for "shortcuts" or patterns to avoid full lists mapping each value.
