A string contains only three types of letters A, B, and C, such as aabbbcbcaaa. To find the longest string, the length of the longest string must be the same. For example, the eldest son of aabbbcbcaaa is bcbcaa, which contains two types: A, B, and C.
Implement the following C ++ functions:
The following is an O (n) implementation method.
Int getmaxlen (string SRC)
#include
Returns the maximum length of a string that matches all characters.
