Q1) Write a method that checks whether two words are anagrams. Two words are anagrams if they contain the same letters in any order. For example, "silent" and "listen" are anagrams. Write a test program that prompts the user to enter two strings and, if they are anagrams, displays "anagram", otherwise displays "not anagram".
Note: The header of the method is as follows:
public static boolean isAnagram(String s1, String s2)
Sample Input #1:
Enter two strings:
Silent
listen
Sample Output #1:
The string “Silent” and “listen” are anagrams.
Sample Input #1:
Enter two strings:
teach
peach
Sample Output #1:
The string “teach” and “peach” aren’t anagrams.
Problem Description:
In the Whimsical Library, each book is enchanted with a magical code to ensure the
protection of knowledge. The validation process for these magical codes involves a
combination of mathematical spells.
The validation process is described as follows:
Take the sum of the digits at odd positions from left to right.
Take the sum of the squared digits at even positions from left to right.
If the absolute difference between the results from step 1 and step 2 is a prime
number, the book code is considered valid; otherwise, it is invalid.
Example 1:
Consider the magical book code 86420137.
Step 1. Take the sum of the digits at odd positions from left to right.
8+4+0+3=15
Step 2. Take the sum of the squared digits at even positions from left to right.
6^2+2^2+1^2+7^2=36+4+1+49 = 90
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
115-901 75 (not a prime number)
Book code 86420137 is invalid.
Example 2:
Now, let's examine the…
Broken Cabins
Problem Statement:
There is an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired.
You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1.
You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap.
Time is money, so you want to cut at most k continuous
pieces of tape to cover all the broken cabins. What is the
minimum total length of these pieces?
Input Format
The first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can use
The second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing…
