Given a 26 letter character set, which is equivalent to character set of English alphabet i.e. (abcd….xyz) and act as a relation. We are also given several sentences and we have to translate them with the help of given new character set.
New character set : qwertyuiopasdfghjklzxcvbnm Input : "utta" Output : geek Input : "egrt" Output : code
Idea behind conversion of new character set is to use hashing. Perform hashing of new character set where element of set is index and its position will be new alphabet value.
Given New character set = “qwertyuiopasdfghjklzxcvbnm”
- First character is q, during hashing we will place ‘a’ (for position ) at index q i.e. (17th).
- After hashing our new character set is “kvmcnophqrszyijadlegwbuft”.
- For input “egrt” =
hash[e -‘a’] = c
hash[g -‘a’] = o
hash[r -‘a’] = d
hash[t -‘a’] = e
For “egrt” is equivalent to “code”.
1.Initialize two strings, one with actual set of alphabets and another with modified one.
2.Get the string to be converted from the user.
3.Retrive the first element of the string, find its index in the modified set of alphabets(eg:0 for ‘q’).
4.Find the element of same index in the actual set of alphabets and concatenate it with the result string.
5.Repeat the above steps for all the remaining elements of the input string.
6.Return the result string.
