Consider the following implementation of the compareTo() method for String. How does the third line help with efficiency? public int compareTo(String that) { if (this == that) return 0; // this line int n = Math.min(this.length(), that.length()); for (int i = 0; i < n; i++) { if (this.charAt(i) < that.charAt(i)) return -1; else if (this.charAt(i) > that.charAt(i)) return +1; } return this.length() - that.length(); }

We want to build 10 letter “words” using only the first n=9n=9 letters of the alphabet. For example, if n=5n=5 we can use the first 5 letters, {a,b,c,d,e}{a,b,c,d,e} (Recall, words are just strings of letters, not necessarily actual English words.) How many of these words are there in total? How many of these words contain no repeated letters? How many of these words start with the sub-word “ade”? How many of these words either start with “ade” or end with “be” or both? How many of the words containing no repeats also do not contain the sub-word “bed”?
Consider the following method: public boolean isprefix(String s1, String s2) {int i = 0;if(s1.length > s2.length) return false;while(i < s1.length) {if(s1[i] != s2[i])return false;i++;}return true;} Exactly how many lines of code (statements) are executed by the method isprefix() in the worst case? Express your answer in terms of n, the length of the string s1. Hint: simplify your final answer as much as possible, and do not put spaces in your answer. Use juxtaposition for the multiplication operator, for example to write "nine times n" write "9n" not "9xn" or "9*n"; to write "four times (n+2)" write "4(n+2)", not "4x(n+2)" or "4*(n+2)". Do not write your answer in Big-O notation. Write the exact number of lines executed.
Write a short recursive Java method that determines if a string s is a palindrome, that is, it is equal to its reverse. Examples of palindromes include 'racecar' and 'mom'. Test the method by asking the user to provide string entries to be checked. Hint: Check the equality of the first and last characters and recur (but be careful to return the correct value for both odd and even-length strings).
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which has an index, n (starting at 0), as a parameter and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: fibonacci(7) is 13
