Asked in companies
You are provided with the two strings named X and Y respectively. Y has its own specific order and has no repeating characters. Your task is to arrange the characters of the first string i.e. X in such a way that the order of characters in X is exactly the same as in Y, which means if ‘d’ occurs after ‘c’ in Y then it should also occur after ‘c’ in X ( obviously if X has ‘d’ and ‘c’ as characters in it ). All you have to do is, convert string X in the specific order with respect to string Y.
Note :
Both the strings have only lowercase English alphabets.
There may be more than one correct solution, you have to return any one of the possible solutions.
Problem approach
We will store the frequency of every character of ‘S’ in a bucket array, then we will loop through ‘REFERENCE’ and will check if that character is present in the ‘S’ or not. If it is present, we will add the character in our final string (the number of times it occurs in ‘S’) and will make the frequency of that character zero in the bucket array. Now for the remaining characters, we will run a loop again through ‘S’, check elements whose frequency is not zero, and add them to our final answer string.
2. Java based questions
Collections, multithreading, SQL query
