An algorithm is designed to extract the protocol prefix from a uniform resource locator (URL) string.
protocol ← ""
k ← 0
WHILE url[k] ≠ ":" AND k < 6
protocol ← protocol + url[k]
k ← k + 1
ENDWHILE
isWeb ← False
IF protocol = "http" OR protocol = "https" THEN
isWeb ← True
ENDIF
Select the most appropriate data type for the variable k used in this algorithm.
