Write atoi. Write a function that takes in the head of two linked lists and returns a pointer to their intersection, if there is one. Can be done in linear time... Write a function to reverse the endianness of a uint32_t. Homework: Write a program in c or c++ that take in binary plain text on stdin and outputs cipher text, encrypted by xor-ing the plain text with a rotating key, on stdout. The program had to be multithreaded using a variable number of threads specified as a command line argument. No matter how many threads are specified, the output has to be the same. The key file is specified on the command line. The plaintext isn't necessarily a multiple of the key length.
