34. Generating permutations
The chapter emphasizes the concept of backtracking, specifically focusing on generating permutations systematically. By understanding how to generate the next permutation of a sequence, the principles of searching for solutions in problems like the n-queens can be effectively applied. The process involves identifying patterns within sequences and ensuring that every possibility is explored efficiently.

What we have learnt
- Backtracking is a systematic search for solutions.
- Permutations can represent the arrangement of elements and can be generated using specific algorithms.
- The next permutation can be discovered through analysis of the sequence order.
Key Concepts
- -- Backtracking
- A methodical approach used to explore all the possible configurations to find solutions, reverting steps upon reaching dead ends.
- -- Permutation
- An arrangement of all or part of a set of objects, where the order of arrangement contributes to different variations.
- -- Suffix
- A trailing segment of a sequence that is examined to determine potential increments in permutation generation.
- -- Dictionary Order
- A method of ordering sequences or words as they would appear in a dictionary, typically used in the context of permutations.
