Machine Conditional Rearrangement Hard

Machine Conditional Rearrangement problems apply different rearrangement rules based on the properties of elements. For example, words longer than 4 letters go to the left, or numbers with digit sum > 10 go to the front. These problems test your ability to apply conditional logic in sequential transformations.

Introduction to Machine Conditional Rearrangement Hard

Machine Conditional Rearrangement problems apply different rearrangement rules based on the properties of elements. For example, words longer than 4 letters go to the left, or numbers with digit sum > 10 go to the front. These problems test your ability to apply conditional logic in sequential transformations.

Prerequisites

Basic rearrangement concepts Conditional logic understanding Property detection (vowel, length, digit sum) Pattern recognition
Why This Matters: Machine Conditional Rearrangement problems appear in 1-2 questions in Banking PO mains and SSC CGL exams. They test conditional logic application.

How to Solve Machine Conditional Rearrangement Hard Problems

1

Step 1: Identify the condition used for rearrangement (e.g., length > 4, starts with vowel, digit sum > 10)

2

Step 2: Determine what happens to elements satisfying the condition

3

Step 3: Determine what happens to elements NOT satisfying the condition

4

Step 4: Apply the conditional rule to the input

5

Step 5: Track how elements are repositioned

6

Step 6: Verify the rule is applied consistently

7

Step 7: Present the output

Pro Strategy: First identify the condition and the action for elements meeting it. Sort or group elements based on whether they satisfy the condition. The relative order within each group may be preserved or further sorted.

Example Problem

Example: Input: 'cat elephant dog ant butterfly'. Rule: Words with length >4 go to left, others to right. Find output. Solution: Step1: Words with length >4: 'elephant'(8), 'butterfly'(9) Step2: Words with length ≤4: 'cat'(3), 'dog'(3), 'ant'(3) Step3: Output: 'elephant butterfly cat dog ant' Answer: elephant butterfly cat dog ant

Pro Tips & Tricks

  • Conditions often involve: word length, first letter (vowel/consonant), digit sum, even/odd numbers
  • Elements satisfying condition may go to left, right, or be interleaved
  • The relative order within each group may be preserved or sorted
  • Multiple conditions may be applied sequentially
  • Check if the condition is applied to all elements or only to specific positions
  • For digit sum, calculate sum of digits for each number

Shortcut Methods to Solve Faster

Group1 = [x for x in input if condition(x)]
Group2 = [x for x in input if not condition(x)]
Output = Group1 + Group2 (if condition elements go left)
Output = Group2 + Group1 (if condition elements go right)
Within each group, maintain original order unless specified otherwise

Common Mistakes to Avoid

Applying condition to wrong property (e.g., word length vs letter count)
Forgetting that digit sum requires summing individual digits, not the number itself
Misidentifying vowels (A, E, I, O, U only - Y is consonant unless specified)
Not preserving relative order when required
