Palindrome Sorting Medium

Palindrome Sorting problems present a sequence of words as input. Palindromic words (words that read the same forwards and backwards) are placed first, followed by non-palindromic words, with each group sorted alphabetically. These problems test your ability to identify palindrome property and apply grouping rules.

Introduction to Palindrome Sorting Medium

Palindrome Sorting problems present a sequence of words as input. Palindromic words (words that read the same forwards and backwards) are placed first, followed by non-palindromic words, with each group sorted alphabetically. These problems test your ability to identify palindrome property and apply grouping rules.

Prerequisites

Palindrome concept (word = reverse of itself) Alphabetical sorting Grouping and classification Word reversal ability
Why This Matters: Palindrome Sorting problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test word property recognition and sorting skills.

How to Solve Palindrome Sorting Medium Problems

1

Step 1: Identify which words are palindromes (word equals its reverse)

2

Step 2: Separate palindromic and non-palindromic words

3

Step 3: Sort palindromic words alphabetically

4

Step 4: Sort non-palindromic words alphabetically

5

Step 5: Concatenate palindromes first, then non-palindromes

6

Step 6: The final output is the combined sequence

7

Step 7: Verify palindrome status for each word

Pro Strategy: Check each word to see if it reads the same forwards and backwards. Group palindromic words together and non-palindromic words together. Sort each group alphabetically. Palindromic words come first in the final output.

Example Problem

Example: Input: 'madam level hello racecar world' Palindromes: 'madam', 'level', 'racecar' Non-palindromes: 'hello', 'world' Sorted palindromes: 'level', 'madam', 'racecar' Sorted non-palindromes: 'hello', 'world' Final: 'level madam racecar hello world' Answer: level madam racecar hello world

Pro Tips & Tricks

  • A palindrome reads the same forwards and backwards: 'madam', 'racecar', 'level'
  • Single-letter words are always palindromes (e.g., 'a', 'b')
  • To check if a word is a palindrome, compare word == word[::-1]
  • Case matters - 'Madam' with capital M is not a palindrome (case-sensitive in puzzles)
  • Palindromes can have odd or even length
  • Common palindromes: 'radar', 'civic', 'noon', 'deed', 'refer'

Shortcut Methods to Solve Faster

Final output = sorted(palindromes) + sorted(non_palindromes)
If a word equals its reverse, it's a palindrome
Palindromes are placed first, then non-palindromes
Each group is sorted alphabetically independently

Common Mistakes to Avoid

Misidentifying palindromes (e.g., 'hello' is not a palindrome)
Forgetting to sort each group alphabetically
Putting non-palindromes before palindromes
Case sensitivity issues (all words are typically given in same case)
