Question
Chapter 21.6, Problem 21.6.3CP
Program Plan Intro
Map:
Map is an interface which contains values on the basis of key and a value pair and represents a mapping between them. Each key and a value pair in the map are unique.
A map can be of three types: HashMaps, LinkedMaps and TreeMaps.

Please can you tell me if this is true or false?
The map(callback [, thisArg]) method returns the index of the first element in the array that passes a test in thecallback function.
True
False
Practice / First Non-Repeating Vowel
Given a string, write a method to find the first non-repeating vowel (a, e, i, o, u) in it and return its index.
● If it doesn't exist, return -1.
● Assume that all the characters of the String is lowercase.
Do not use String class functions other than charAt() and length()
You can also try to solve with Map data structure like using a Map variable.
●
Example
input: google
output: 5
explanation: only e is
non-repeated vowel and it's
index is 5
Example
input: mood
output: -1
explanation: o is repeated, no
non-repeating vowel.
Example
input: responsible
output: 4
explanation: e is repeated, o
and i are not repeated, o is the
first non-repeating vowel
Modify the algorithm described in the class to calculate the longest palindrome,
such that there is enough information on the table to build the longest palindrome
from the table. Hint: You can use similar data structure used for Longest common
subsequence.
Explain how you can rebuild a longest palindrome from the given string using this
data structure.

- 4. This question involves the process of taking a list of words, called wordList, and producing a formatted string of a specified length. The list wordList contains at least two words, consisting of letters only. When the formatted string is constructed, spaces are placed in the gaps between words so that as many spaces as possible are evenly distributed to each gap. The equal number of spaces inserted into each gap is referred to as the basic gap width. Any leftover spaces are inserted one at a time into the gaps from left to right until there are no more leftover spaces. The following three examples illustrate these concepts. In each example, the list of words is to be placed into a formatted string of length 20. Example 1: wordList: ["AP", "COMP", "SCI", "ROCKS"] Total number of letters in words: 14 Number of gaps between words: 3 Basic gap width: 2 Leftover spaces: 0 Formatted string: 2 0 1 A A|P| | 3 Basic gap width: 1 Leftover spaces: 2 Formatted string: 0 1 G R Example 2:…arrow_forwardjava Write a method that returns the frequency of each characters of a given String parameters If the given String is null ,then return null, if is empty then return an empty Map.
