These sheets were ordered based on difficulty. Each sheet contains ~100 problems. For the last sheet [phase-1-basic-programming](https://github.com/cs-MohamedAyman/Problem-Solving-Training/tree/master/level-1/hackerearth-phase-1-basic-programming) that focus on the basic programming problems, It's divided into 4 classes of problems (Input/Output - Bit Manipulation - Recursion - Operators). Also, this sheet was ordered based on the problem difficulty and grouped by the problem type. Finally, this sheet contains ~130 problems.

 * On each one of these sheets has an excel sheet to record your effort and enhance your progress, The time estimate for level problems is between ***30 min to 45 min*** for each problem, including ***reading time, thinking time, coding time, debugging time, and learning time***.
