Odd-Even Separation Easy
Odd-Even Separation problems present a sequence of numbers as input. Through a series of steps, even numbers are moved to the front (or back) of the sequence, followed by odd numbers, often with each group sorted internally. These problems test your ability to classify numbers by parity and arrange them systematically.

Introduction to Odd-Even Separation Easy
Odd-Even Separation problems present a sequence of numbers as input. Through a series of steps, even numbers are moved to the front (or back) of the sequence, followed by odd numbers, often with each group sorted internally. These problems test your ability to classify numbers by parity and arrange them systematically.
Prerequisites
How to Solve Odd-Even Separation Easy Problems
Step 1: Observe the given input sequence of numbers
Step 2: Analyze the transformation pattern in the provided steps
Step 3: Identify whether evens go first or odds go first
Step 4: Determine if each group is sorted internally
Step 5: Apply the same separation logic to continue the sequence
Step 6: The final output has all evens (sorted) followed by all odds (sorted) or vice versa
Step 7: Verify the parity of each number
Example Problem
Example: Input: '15 42 28 91 56' Step 1: '42 28 56 15 91' Step 2: '28 42 56 15 91' Final Output: '28 42 56 15 91' Solution: Step 1: Even numbers (42,28,56) moved to front Step 2: Evens sorted ascending: 28,42,56; odds (15,91) remain Answer: 28 42 56 15 91
Pro Tips & Tricks
- Even numbers: divisible by 2 (last digit 0,2,4,6,8)
- Odd numbers: not divisible by 2 (last digit 1,3,5,7,9)
- Evens can be sorted ascending or descending
- Odds can be sorted ascending or descending
- The order of evens and odds (which comes first) is fixed in the pattern
- Count how many numbers are even and how many are odd to verify final arrangement
