In SAP Interview, Questions are pretty simple and straight forward, easy to code but they ask you to write proper unit test cases and they check if you have handles all edge cases or not.
SAP Interview Question # 1
Complete the code to solve the following problem statement
Given two integers N and M (0 <= N <= M <= 10 7), find the sum of digits of all integers from N to M, both inclusive. Example: Input: 1 10 Output: 46
SAP Interview Question # 2
Planning the street
King Kohima has reserved a new exclusive street for his executive class employees where they can build their homes. He has assigned you to plan that street. You have to decide on which plots along the street are new building allowed to be built. In order to this, you first want to calculate the number of possible ways of assigning free plots to buildings while keeping in mind this restriction – No two consecutive plots can have buildings on them. This is done to ensure a sense of free space in the arena. The street is divided in M sections. Each section corresponds to 2 plots, one on each side of the street. Find the number of possible assignments. Input In the first line you’re given M ( M ≤ 1000 ). Output In the first and only line output the result/ Example Input: 3 Output: 25 Example explanation: If we just look at the one street side and mark X as a plot where building is allowed and Y as a free plot, we have: XYX, YXY, YYX, XYY, YYY. Since the same number exists on the other side, we have 5*5 = 25 combinations.
Tips to crack SAP Interview Questions
a) Data Structures and Algorithms Made Easy: Data Structures and Algorithmic Puzzles, Fifth Edition ( Ex. Amazon, Microsoft and My Friend) : This book is best for college grads, As this book starts with simple basic fundamentals of data structure and algorithm, and gradually very good and tough questions with explanation this book covers, so basically after completing this book You can think how to use and modify any existing data structure and algorithm for your question.
b) Cracking the Coding interview by Gayle Laakmann McDowell this book is for good coders and for those who understand reuse of exiting data structure properly, This book contains best logical and complex questions on Data Structure and Algorithm.
