The nice touch is that it comes with apples and oranges, in case you’ve missed those primary school math exercises with fruits. Problem Statement Sam’s house has an apple tree and an orange tree that yield an abundance of fruit. s: starti... POD #3 – Grading Students2025-09-29T10:00:00+03:00 2025-09-30T11:44:53+03:00 https://www.dolhescu.com/posts/grading-students/ Petru Dolhescu It’s Tuesday, the second day of the week, but we are already at Problem #3. That’s because I started this series last Friday, following a simple principle of motivation and discipline: start today, not tomorrow. Don’t wait for Monday to begin.

Just 10–15 minutes of focused problem-solving to wake up the brain before diving into real work. Today’s Problem of the Day (POD) is a classic one from HackerRank: finding the first occurrence of a number in a sorted array. Problem Statement Given a sorted array of integers that may contain d...

You can scale down all components to minimize costs during this time. Without a central source of truth, unintended changes to the infr...
