Scan an integer and print the alphabet so that: 1-A; 2-B...26-Z; 27-AA,28-AB,29-AC...52-AZ; 53-AAA,54-AAB,55-AAC...78-AAZ...etc.. If you provide an integer, say 28-it should print AB. If you scan another integer say 55, it should show AAC
Given two (dictionary) words as Strings, determine if they are isomorphic. Two words are called isomorphic if the letters in one word can be remapped to get the second word. Remapping a letter means replacing all occurrences of it with another letter while the ordering of the letters remains unchanged. No two letters may map to the same letter, but a letter may map to itself. Example: Given "foo", "app"; returns true we can map 'f' -> 'a' and 'o' -> 'p' Given "bar", "foo"; returns false we can't map both 'a' and 'r' to 'o' Given "turtle", "tletur"; returns true we can map 't' -> 't', 'u' -> 'l', 'r' -> 'e', 'l' -> 'u', 'e' -'r' Given "ab", "ca"; returns true we can map 'a' -> 'c', 'b'
