In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn t kept waiting any longer than necessary for the relatively slow disks.
Problem Statement
You are given a string input. You are to find the longest substring of input such that the reversal of the substring is also a substring of input. In case of a tie, return the string that occurs earliest in input.
Definition
Class: ReverseSubstring
Method: findReversed
Parameters: string
Returns: string
Method signature: string findReversed(string input)
(be sure your method is public)
Notes
The substring and its reversal may overlap partially or completely.
The entire original string is itself a valid substring (see example 4).
Constraints
input will contain between 1 and 50 characters, inclusive.
Each character of input will be an uppercase letter ( A - Z ).
Examples
0)
"XBCDEFYWFEDCBZ"
Returns: "BCDEF"
We see that the reverse of BCDEF is FEDCB, which appears later in the string.

CCS編程環境 使用的是匯編加C的混合編程方法：
The programme of the Correlation Algorithm.
Using INT2 to get the input signal.
Array x, in first step, is the input signal produced by programme,
in next step, is the input signal get from A/D,
the length is 128, 32-bit floating point.
Array y, in first step, is the input signal produced by programme,
in next step, is the input signal get from A/D,
the length is 128, 32-bit floating point.
Array cor is the Correlation result, the length is 255, 32-bit floating point.
