CuiZewen wants to merge 3 commits into namin:master from CuiZewen:master

CuiZewen commented Jun 10, 2020

In the past, there is only greedy quantifiers(.) , so i add the lazy quantifiers(.?)

The first tries first to repeat then backtracks to following pattern, the second tries first the following pattern then backtracks to repeat.

for example on the string "abab"
a.b will match "abab", a.?b will match only the starting "ab" :)
