Topics requirements:
Given two binary string, and return to their (expressed in binary).
And a non-empty input string contains only numeric 1 and 0.
answer:
See the whole idea of the problem are: (1) complement: string up into short and long string of the same length; (2) transfer: the string to an integer array; (3) plus: each and adding bits, a full binary; (4) reverse: an array of integers, and then added into a string finished;
But write code super trouble, needs to be improved:
Read the solution to a problem in the idea, really improved a lot, the above ideas can omit several steps: emphasis Ascii coding value can not convert the string to an array of integers, the direct use of characters, kneeling kneeling .. ..
