- Insert one letter into one of strings
- Replace one of letters from one of strings with another letter
Input

@abbi_18 At any given point you just require only n-elements, hence you don't need to store n*n elements. If you think in this direction you'll be able to reduce space complexity from O(n^2) to O(n). |

I don't understand. Does insertion and deletion take place only at the end or wherever in between? |
