lol…

  1. Please include link of solution if you are facing problem in converting it to proper format here…

  2. Please include problem link too…

  3. I have a doubt… You want to understand problem or code directly…

  4. Have you tried this problem by yourself? I am not seeing any attempt from your side…

Edit: Thanks @vijju123 for formatting it properly…
