The $\_\_$init$\_\_$ method of OrfFinder must run in time complexity O$($N$2$

$),$ where N is the

length of genome.

$$ Let T be the length of the string start, U be the length of the string end, and V be the

number of characters in the output list $($for a correctly generated output list according to

the instructions in $1\mathrm{.}2),$ then find must run in time complexity $($T $+$ U $+$ V $).$
