Solution/first tweet and water day

[sh3rqxs]

Hii again, here are my solutions for day 20 and day 21.

What I did:

1. First Tweet 🐦

   • Defined 3 variables:

     • charsLeft — the character limit, initialized to 140.
     • count — a running total of characters typed, initialized to 0.
     • string — an array of the tweet's words, split on spaces.

   • Iterated over each word in string using a for...of loop.

   • Applied different character counts based on the type of each word:

     • Usernames (starting with @) → counted as 20 chars.
     • URLs (starting with http:// or https://) → counted as 23 chars.
     • Emojis → counted as 2 chars.
     • Everything else (regular words, punctuation, etc.) → counted normally.

   • Added 1 to count per word to account for the space following it.

   • Returned the remaining characters as charsLeft - count.

2. Water Day 💧

   • Defined 4 variables:

     • currentVolume — the initial volume of water.
     • lossRate — the leak.
     • iterations — the number of hours.
     • waterRemaining — the final volume of water.

   • Created a loop using a classic for loop.

   • Calculated the fixed percentage a pipe loses each hour with → new volume = current volume * (1 - leak/100).

   • Added a condition to return the volume of water remaining after all hours have passed:

     • If the currentVolume >= threshold, returns waterRemaining = Number(currentVolume.toFixed(2)).
     • Else, returns -1.

Let me know if there's anything to fix!
