Python algorithm error when trying to find the next largest value
I think your program is failing because you need to change: _getAvailableID(i) to return _getAvailableID(i) (At the moment the recursive function finds the correct answer which is discarded.) However, it would probably be better to simply put all the ids you have seen into a set to make the program...
Appending lines for existing file in python [duplicate]
The issue is in the code - curr_file = open('myfile',w) curr_file.write('hello world') curr_file.close() The second argument should be a string, which indicates the mode in which the file should be openned, you should use a which indicates append . curr_file = open('myfile','a') curr_file.write('hello world') curr_file.close() w mode indicates write ,...

Why is my linked list only printing last entry?
The problem is the way you are treating the result of strtok: you are setting its value right into the node, instead of copying it. Make a copy of name when adding a node: void push(node ** head, int uid ,char* uname) { node * new_node; new_node = malloc(sizeof(node)); new_node->uid...

How to get rid of .ignore file in Git?

As a general rule of thumb, hardcoding absolute paths makes your program less flexible.

Using such an absolute path will break the application. And as always, no general...
