Question Given two integers low and high representing a range, return the sum of the integers in that range. For example, if low is 12 and high is 18, the returned values should be the sum of 12, 13, 14, 15, 16, 17, and 18, which is 105. If low is greater than high, return 0. Examples: sumRange(12, 18) -> 105 sumRange(1, 5) -> 15 sumRange(1, 100) -> 5050 Answer package com.bbubbush.tistory; publ..

Question We have bunnies standing in a line, numbered 1, 2, ... The odd bunnies (1, 3, 5, ...) have the normal 2 ears. The even bunnies (2, 4, ...) we'll say have 3 ears, because they each have a raised foot. Recursively return the total number of "ears" in the bunny line 1, 2, ... n (without using loops or multiplication). Answer package com.bbubbush.tistory; public class X158 { public static v..

Question Given n >= 0, create an array of length n * n with the following pattern, shown here for n = 3 : {0, 0, 1, 0, 2, 1, 3, 2, 1} (spaces added to show the 3 groups). Answer package com.bbubbush.tistory; import java.util.Arrays; import java.util.stream.Collectors; public class X119 { public static void main(String[] args) { int n; n = 3; System.out.printf("[n = %d]\n", n); printArray(squareU..

Question Given a string, return a new string made of 3 copies of the last 2 chars of the original string. The string's length will be at least 2. Answer public class X121 { public static void main(String[] args) { String str = ""; str = "Hello"; System.out.printf("[str = %s]\n", str); System.out.println(extraEnd(str)); str = "Hi"; System.out.printf("[str = %s]\n", str); System.out.println(extraE..

Question Given two strings, word and a separator sep, return a big string made of count occurrences of the word, separated by the separator string. Answer public class X125 { public static void main(String[] args) { String word = ""; String sep = ""; int count = 0; word = "Word"; sep = "X"; count = 3; System.out.printf("[word = %s, sep = %s, count = %d]\n", word, sep, count); System.out.println(..
