#

this is 3sum problem, pretty simple

#

but how did his code pass?

#

what if there will be input: [-14,-1,2,3,6,7,8,10]

#

and his target will be 6

#

his front will be 7, and it will always decrease

#

this way, he wont be able to find combination [8, - 14, 6]

#

cause 8 is out of range

#

is there something i am missing?
