After starting with EIF, the time is working differently for me.

So our exams started and when I was at the section to write the date in the answer sheet,I couldn’t remember that day’s date, I had an existential crisis at that moment, I asked the person on the next bench today’s date and then wrote it with a wrong month (Based on true events).

Thinks Accomplished this week :

*   Added SafeMath library for arithmetical operations on smart contract variables for my smart contract.
    
*   Created a mechanism that returns all the eligible participants so that we can choose winners among them and also return the interest generated by the stake.
    
*   Created a function to increase the balance of winners of the lottery.
    
*   Started working on frontend of the project.
    
*   Plammed about what things to implement next week.
