Amortized Analysis
In computer science, amortized analysis is a method of analyzing algorithms that considers the entire sequence of operations of the program. It allows for the establishment of a worst-case bound for the performance of an algorithm irrespective of the inputs by looking at all of the operations. At the heart of the method is the idea that while certain operations may be extremely costly in resources, they cannot occur at a high-enough frequency to weigh down the entire program because the number of less costly operations will far outnumber the costly ones in the long run, "paying back" the program over a number of iterations. It is particularly useful because it guarantees worst-case performance rather than making assumptions about the state of the program. [wikipedia]

CTCI: Ch. 1-8
Assume you have a method isSubstring which checks if one word is a substring of another. Given two strings, s1 and s2, write code to check if s2 is a rotation of s1 using only one call to isSubstring (i.e., “waterbottle” is a rotation of “erbottlewat”).
CTCI: Ch. 1-5
Implement a method to perform basic string compression using the counts of repeated characters. For example, the string aabcccccaaa would become a2b1c5a3. If the “compressed” string would not become smaller than the original string, your method should return the original string.
CTCI: Ch. 1-4
Write a method to replace all spaces in a string with ‘%20’. You may assume that the string has sufficient space at the end of the string to hold the additional characters, and that you are given the “true” length of the string. (Note: if implementing in Java, please use a character array so that you can perform this operation in place.)
EXAMPLE
Input: “Mr John Smith ”
Output: “Mr%20John%20Smith”
CTCI: Ch. 1-3
Given two strings, write a method to decide if one is a permutation of the other.
Android Remote Control for net-TV3
This app uses wireless network to connect your PC and then sends commands to control your player software. Now, it only supports UPMOST net-TV3 (network TV-BOX).
Development tool:
- Server: Embarcadero C++ Builder XE3
- Client: Eclipse with Android SDK
- Testing Platform: HTC Desire HD (Android 2.3.4)
