APT: Johnsort

Class

public class TheBestName { public String[] sort(String[] names) { // fill in code here } }

Problem Statement

As some of you may know, there is no name better than JOHN. Let's define the rules for comparing names. Each letter has a weight ('A' - 1, 'B' - 2, ..., 'Z' - 26). The weight of a name is the sum of the weights of all its letters. For example, the name MARK has weight 13 + 1 + 18 + 11 = 43.

When comparing two names, the one with the larger weight is considered better. In case of a tie, the one that comes earlier lexicographically is better. But there is one exception - the name JOHN is the best name of all.

You are given a String[] names, each element of which contains a single name. Sort the names from best to worst and return the sorted String[].

Constraints

Examples

  1. 
    {"JOHN", "PETR", "ACRUSH"}
    
    Returns: {"JOHN", "ACRUSH", "PETR" }
    
    
    PETR has weight 59, ACRUSH has weight 70 and JOHN has a weight of only 47. But nevertheless JOHN is the best name, ACRUSH takes second place and PETR is the last.

  2. 
    {"GLUK", "MARGARITKA"}
    
    Returns: {"MARGARITKA", "GLUK" }
    
    
    MARGARITKA is definitely better than GLUK.

  3. 
    {"JOHN", "A", "AA", "AAA", "JOHN", "B", "BB", "BBB", "JOHN", "C", "CC", "CCC", "JOHN"}
    
    Returns: 
    {"JOHN",
    "JOHN",
    "JOHN",
    "JOHN",
    "CCC",
    "BBB",
    "CC",
    "BB",
    "AAA",
    "C",
    "AA",
    "B",
    "A" }
    
    
    AA and B both have the same weight, but AA is better as it comes earlier lexicographically. For the same reason, AAA is better than C and BBB is better than CC.

  4. 
    {"BATMAN", "SUPERMAN", "SPIDERMAN", "TERMINATOR"}
    
    Returns: {"TERMINATOR", "SUPERMAN", "SPIDERMAN", "BATMAN" }
    
    
    Here are some superheroes sorted by their names.
