Hackerrank - Women's codesprint #3

Introduction

Julia learned the importance to go out more often, and she chose to go to the meetup called the tech & startup weekly in downtown, so she spent time from 6:30pm to 8:00pm to meet people. Actually she started to work on the contest around 9:00pm.

But she still made a lot of errors, and took more than 3 hours to code the first medium algorithm.

Here is the progress she made so far, 3/11/2017  12:46AM. She will go to sleep and then after a good night sleep, she will try to work on the other 2 medium algorithm and one hard algorithm.

She finished the first 3 algorithm and solved all of them successfully, score 70.00 so far.

Hackathon Shirts

She spent a few hours on Hackathon Shirts. She thought about test cases she should choose more carefully. Two algorithms are involved, one is merging interval algorithm, the other is binary search algorithm. Very good workout.

Facts to share

Julia still made a bug in her writing after 4 - 5 times to practice merging intervals as an algorithm. Why? Because she depends on her memory of the algorithm, do not start from the beginning of analysis, what test cases she should cover when she finishes the coding. She missed the previous interval end value, she should check maximum of two values instead.

Julia,
rely on your past practices,
it is not to test how good your memorize the algorithm.
But always,

always guard with 

the reasoning, 

test cases. 

Remember your sinking sand lessons.

Choosing Recipes

Work on the Choosing Recipes algorithm starting from 11:30am - 4:13pm, very close to a workable solution.  It just took more than 3 hours to figure out the ingredient purchase only need counting once.

Once Julia knows the tough part of the algorithm, she took greedy approach and used recursive solution to make a quick points first, she made it 29 points, her algorithm passed first 7 test cases but failed test cases from 8 to 12.

Julia scored 29 points out of maximum score 50, at 5:49pm. There are still 14 hours to go, actually she has 6 hours before 12:00am. She has to make decision to continue on this algorithm, or move to next medium algorithm, last hard algorithm.

During our press hours we are not doing only interviews, we practice our other skills ☺️☺️☺️☺️🤗 во время общения с прессой, мы не только говорим , но ещё и практикуем разные способности ... 🙈😊😌 🎬🎬🎬
