- Lexicographical ordering of numbers focuses on digit comparison, similar to string comparison 🏘️
- Recursive approach is employed to generate numbers in lexicographical order ♻️
- Base case triggers when the generated number exceeds the input limit 'n' 🛑
- The algorithm explores all possible combinations of digits, multiplying the current number by 10 and adding digits 0-9 🔟
- Time complexity is linear as each number is visited only once 🚄
- Space complexity is logarithmic due to recursion, with the tree height being log base 10 of 'n' 🌳
