Want to calculate all sum of all possible paths from root to leaf, each node has value of a integer number (decimal). In the following example,
1
/ \
2 4
/ /\
3 5 6
possible paths are (123, 145, and 146, which sum is 414). In this example, 12 is not a valid path since 2 is not a leaf node....

I have javascript code that repeats this pattern many times (though the values of INSTRUCTIONS and "a" are different each time). The number of elements in "INSTRUCTIONS" varies.
var INSTRUCTIONS = [ 'LEFT', '90', 'FORWARD', '10', 'LEFT', '90'];
var a = [
'red',
'blue',

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.
What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

Due to my needing to use C libraries inside C++, I kept finding myself wanting to be able to ensure that the free function got called, even if an exception got thrown. UTILS_SCOPE_EXIT ensures that the function will be called at the end of scope. External documentation shows how to use it, and al...
I'm working on a fork of Cygwin for native Windows development.
In this commit, I'm trying to improve the security of code that spawns cmd.exe, used by functions like system, popen.
What I would like to focus on is this:
static const char *cmd_exe_path = NULL;
static void init_cmd_exe_path(vo...
Problem
Count the number of character replacements necessary to convert an input String to a palindrome.
Each character replacement must replace the given character with the character directly before it in the alphabet (sorted A-Z).
In other words, D can only be replaced with C.
For simplicit...
The code below takes a filled out Sudoku board of size NxN, with sub-blocks of nxn, and checks if the solution is correct.
main_function takes a board as input. This function calls check_rows and check_blocks. The first of the two is used to check both the rows and columns of the board. The seco...
A cricketer can score 1, 2, 4 or 6 in a ball. Find in how many ways the player can score a total of "n" runs without hitting 3 consecutive boundaries. Note: Scoring 4 or 6 is considered as a boundary.
My solution is:
int *arr; //global array to save calculated ways
int waysUtil(int n, int boun...
I'd like to split an input string on the first colon that still has characters after it on the same line.
For this, I am using the regular expression /:.+/
So given the string
aaa:
bbb:ccc
I'd expect an output of
["aaa:\nbbb", "ccc"]
And given the string
aaa:bbb:ccc
I'd expect an outpu...
My program is made to tell the positions of each word in a sentence. However it simply doesn't work sometimes and I cannot tell why.
counter = 0
mainLoop = True
print ("this program takes a sentence and a word and puts outputs the positions of the words in the sentence")
sentence = str(input("i...

I created an application where you need to push invisible buttons in a certain order to unlock the advanced mode. To handle this, I wanted to use a queue (FIFO) of my own, adapted to my problem.
Every time I click a button, its ID is added to the queue with addItem, and the pas...
I have been writing an event class for my game engine and I came across to the following problem:
Is casting a base class object to a derived class object given a type flag a good programming design?
Let me give you the following simple example. I have this enum holding the categories of the e...
The intent is to have an auto_increment composite primary key on a InnoDB table which mimics the behavior as on a MyISAM table. The following assumes (3) InnoDB tables all with an auto_increment composite primary key (id incrementing and a_id not incrementing). Please comment positively or nega...
