can you plz start course for snap important problems
1. MACHINE INPUT-OUTPUT INTRODUCTION

2. About Me .I hold a B.E degree in Electronics & Communication Engineering. . CAT, 17: DI & LR-98.29 %ile. Follow me on the Unacademy learning app for all conceptual courses and practice papers on DI 8 LR topics for CAT and other B-school entrance exams: https://unacademy.com/user/iriyaagarwal . Not al1 are born Einstein's but trust me with hard work and dedication we can together make it possible.

3. MACHINE INPUT-OUTPUT INTRODUCTION

4. WHAT IS INPUT OUTPUT? Machine input or Input Output is a question type, where the candidate is given some kind of word and number arrangement. With each subsequent operation, the arrangement of the words and numbers changes. These operations are performed until a final arrangement is reached or is performed in loop. The student is required to identify the hidden pattern in the rearrangement and apply it to the questions.

5. ABOUT INPUT OUTPUT QUESTIONS Questions relating to machine input-output or simply input-output are a series of statements in different steps and is stated in jumbled manner. It is a kind of computer or word- processing machine and this machine performs some operations on the input that is given. The machine operates repeatedly according to a predetermined pattern. These types of questions are normally asked in reasoning topics. These questions may look tough but actually they are very easy. We have to just look the input line and compare it with the end step line and after comparison we can make an idea of the machine's performance. After plotting the idea, we can start from the first step to understand the orientation of the steps.

6. TIPS ABOUT NUMBER OF STEPS .If there are 'n' words/digits in the input then at most 'n-1' steps are required to rearrange it completely. .Number of words/digits arranged until the present step is greater than or equal to the present step number. If input is not given we cannot determine the previous step from given step number or we cannot determine input from given step number.
