i need write method public int sublist (charlist list) gets list , returns how many times list exist.

for example:

my list a b c d b g e

parameter list ita b return 2.

my list b b b b

parameter list b b return 3.

the method should efficient possible.

currently problem don't know mean when efficient possible, if loop through list n times, , everytime find same character loop on both list , go o(n^2)? there better way make o(n) or below?

this in effective searching string in string, o(n) complexity

and find first occurrence can keep looking next occurrence in remaining list it's still o(n) find occurrence
