Given a set of n nuts of different sizes and n bolts of different sizes. There is a one-one mapping between nuts and bolts. Comparison of a nut to another nut or a bolt to another bolt is not allowed. It means nut can only be compared with bolt and b…

1. Convert string from "AAABBCC" to "A3B2C2". 当面试者提出这个问题的时候,首先需要确认题意:譬如:字符串是不是顺序的,是否有字符重复出现. 例如: ABBAACB , AAABBCCCBBAA. 如果是顺序的话可以一次遍历字符,如果是杂序的话,需要2次遍历. C#里面采用Dictionary是很方便的. public static string CountCharNumber(string input) { Dictio…
