Jan 12 - Daily Programming Diary

00:40

Starting to migrate Raahee Blog to Markdown.

21:00

It's been a whole day of work and I haven't written anything yet, so I'm gonna divide this into subsection with the work that I did.

Raahee

I worked on Raahee till approximately 4:30. The majority of that time was taken by actually looking for the best choice of markdown for our use case. Since none of the Markdown Editors I found had internal link support, I decided to pick rich-markdown-editor for the simple reason that people writing the blog may not be having knowledge to write Markdown using syntax, so this allows for them to modify using mouse. Neat! I know. :)

Today's challenges took a lot of time since I decided to pick up some ambitious projects.

1. The first challenge was playing the chrome dino game. Easy! Yeah!
   Then came the programming challenges.

2. The next challenge I picked was one where we had to build something to save food. In my opinion if you have a good cook, food will never go to waste! 😂
   But I had to develop something. So I made a project that could take input of the ingredients that you have in your fridge/readily available and it will give you recipes according to that. This took me around 2 hours since designing the front-end without Bootstrap and MaterialUI, after being dependent on React for so long was a tough task.

   

3. Then arrived the challenge of making a Tic Tac Toe game. I had built it using Java when I was in first year so I decided to take on JavaScript since that was what I had been working with all day. Also, I didn't have Java SDK and all of that. So I started building and decided to take help in front end from a website, and when I was done, it was already 14:30. Nevertheless, it looked pretty good, but I guess that's what happens when you take someone else's CSS. 😛

   

4. The third programming task of the day was to build a Random Number Generator, and it goes without saying that we couldn't use internal random functions. So I remembered what I had studied in 6th semester about Linear Congruential Generator and decided to write the code for that. Was done with that pretty quickly, cuz you know C++

   Copycopy code to clipboard
   1#include <bits/stdc++.h>
   2using namespace std;
   3
   4int Random(int Xo, int m, int a, int c) {
   5  cout << Xo << " ";
   6  return ((Xo * a) + c) % m;
   7}
   8
   9int main() {
   10  int Xo = 2432;  // Initial value
   11  int m = 134456; // mod
   12  int a = 8121;   // Multiply
   13  int c = 28411;  // add
   14
   15  for (int i = 0; i < 10; i++) {
   16      Xo = Random(Xo, m, a, c);
   17  }
   18
   19  return 0;
   20}

5. Now what turned out to be the most ambitious project of today. Making an app that fetches emotions from facial expressions and gets a song according to that from the Spotify API. This project took almost 2 hours and some sleep. I used face-api.js for the extraction, which was really hard to use but since I had explored it the previous night, it helped me a lot. I know, I know, time for an image.

   

   Don't mind the hand, there was a lot of light coming from behind, so it was behaving a bit finicky.

Well those were all the daily challenges that I decided to pick up for today and it has been a really tiring day.
AND I HAVEN'T DONE TODAY'S LEETCODE CHALLENGE.

Wow, my brain is completely shut down. Took so much time to write code for this simple problem.

Copyadd-two-numbers.cpp: copy code to clipboard
1ListNode *addTwoNumbers(ListNode *l1, ListNode *l2)
2{
3    ListNode *head = NULL, *prev = NULL;
4    int carry = 0;
5    while (l1 || l2)
6    {
7        int v1 = l1 ? l1->val : 0;
8        int v2 = l2 ? l2->val : 0;
9        int tmp = v1 + v2 + carry;
10        carry = tmp / 10;
11        int val = tmp % 10;
12        ListNode *cur = new ListNode(val);
13        if (!head)
14            head = cur;
15        if (prev)
16            prev->next = cur;
17        prev = cur;
18        l1 = l1 ? l1->next : NULL;
19        l2 = l2 ? l2->next : NULL;
20    }
21    if (carry > 0)
22    {
23        ListNode *l = new ListNode(1);
24        prev->next = l;
25    }
26    return head;
27}

I'll attend the event at 22:30 tonight and then sleep. Let's see how many points I have. 🎉

Ciao!
