Recently wrote a brainfuck interpreter in Go. Here's the Github Repo Brainfuck Areas that need work The parsing for brackets [] is still buggy and is known to fail when dealing with nested loops i.e [[]] any hints on how to approach the problem would be greatly appreciated. After looking at this ...

As far as I test, there is no any bug point tested. However, I wonder that if there is a problem with the usage of arr.Length or arr.Length - 1. // size is array length private static int BinarySearch(int[] arr, int element) { int begin = 0; int end = arr.Length; for (; begin < end ;...

String s = input.next(); for (int i = 0; i < s.length(); i++) { char c = s.charAt(i); switch (c) { case '0': System.out.println("zero"); break; case '3': System.out.println("three"); break; case '8': System.out.println("eight"); de...

I'm programming Tic-Tac-Toe using minimax algorithm with alpha-beta pruning after taking Harvard's CS-50. My logic is working perfectly, except for the return time of minimax (especially on the first call, when only one player played). I was thinking of replacing the extra recursive call of minim...

this is a kata from codewars, here is the description of the kata: think of a Quadribonacci starting with a signature of 4 elements and each following element is the sum of the 4 previous, a Pentabonacci (well Cinquebonacci would probably sound a bit more Italian, but it would also sound really a...

I am trying to plot heatmap with three variables x, y and z, each with vector length of 932826. The time taken with the function below is 28 seconds, with a bin size of 10 on each x and y. I have been using another program where the same plot happens in 6 - 7 seconds. Also, I know that the plot f...

The code: #include <iostream> #include <stdio.h> #include <string.h> char filename[] = "11.txt"; char filename1[] = "2.txt"; FILE* ptr, * resultptr; char string[100]; char words[100][100]; int len = sizeof(filename) / sizeof(char); int i = 0, j = 0, k, length, count; int main() { fopen_s(&ptr, ...

Write a code to identify a valid straight of eight cards, e.g. ['4H', '5S', 'AC', '7C', '8H', 'AH', '0S', 'JC']. Note that the card combination may include Wilds (as we see in our example, with the Ace of Clubs standing in for a Six and the Ace of Hearts standing in for a Nine), but must include ...
