昨天剛面完，發一下面經，累積一下人品
一面：
-
Could you introduce yourself and tell me why you are interested in solutions engineer intern?
-
You’re given a string only containing alphabet, number and parenthesis. Please find a valid string (with balanced parenthesis) by removing the fewest characters. (30min)
Example:
“(a())(” -> “(a())”
“(((((” -> “”
“())(” -> “()”
第二題應該是利口散凌伊的變形
