I have String : "extend cup end table"

case 1:If i use patter "e.+d" it will find() match: extend cup end

case 2:If i use patter "e.+?d" it will find() match: extend end

Can someone please let me know what is difference between ".+" and ".+?"

I know that + is one or more and ? is one or zero. But i am not able to understand how does it work.

Thanks. Nakul
