CTCI: Ch. 1-1
Implement an algorithm to determine if a string has all unique characters. What if you cannot use additional data structures?
Chapter 2. Linked Lists
-
Write code to remove duplicates from an unsorted linked list.

How would you solve this problem if a temporary buffer is not allowed? - Implement an algorithm to find the nth to last element of a singly linked list.
-
Implement an algorithm to delete a node in the middle of a single linked list, given only access to that node.
EXAMPLE
Input: the node c from the linked list a->b->c->d->e
Result: nothing is returned, but the new linked list looks like a->b->d->e
Chapter 1. Arrays and Strings
- Implement an algorithm to determine if a string has all unique characters. What if you cannot use additional data structures? [C++]
- Implement a function void reverse(char* str) in C or C++ which reverses a null-terminated string. [C++]
- Given two strings, write a method to decide if one is a permutation of the other. [C++]
-
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.)[C++]
EXAMPLE
Input: “Mr John Smith ”
Output: “Mr%20John%20Smith” Continue reading
8051 Development Tool
Current Features:
- Read a Intel Hex file (compiled by Keil uVision4)
- Generated a memory table which is used to write to AT89S52 microcontroler (8-Bit Microcontroller, 8KB ISP Flash)
- Converted the table into another format: 5F=0; DF=1 (the actual data that will be written to the device)
- Listed all usb devices
Unfinished parts:
- Read/write data from/to AT89S52 microcontroler
