Introduction1

Introduction

  • Linear fashion means arrangement in a row.

  • Analyze the problem and arrange it.

  • Find the direct condition and start to solve, because the remaining conditions are based on the direct condition.

  • No condition for the particular item, shows their is possibility in answer.
