Return an array that is "left shifted" by one--so for an input of {6, 2, 5, 3}, the method returns {2, 5, 3, 6}. You may modify and...

Given a non-empty array of ints, return a new array containing the elements from the original array that come after the last 4 in the...

We'll say that an element in an array is "alone" if there are values before and after it, and those values are different from it. Return...

Return an array that contains the exact same numbers as the given array, but rearranged so that all the zeros are grouped at the start of...

Given two arrays of ints sorted in increasing order, called outer and inner, return true if all of the numbers in inner also appear in ...

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...

Given two strings, word and a separator sep, return a big string made of count occurrences of the word, separated by the separator...

Write a method called listUpper() that takes in a list of strings, and returns a list of the same length containing the same strings but...

Write a method called listSearch() that takes in a target string and a list of other strings. This method returns a (possibly shorter)...

Write a method called listLength() that takes in a list of strings and returns a list of their lengths as integers. You must create a new...

Given a string, return a string where for every char in the original, there are two chars.

Given a string, compute a new string by moving the first char to come after the next two chars, so "abc" yields "bca". Repeat this...

Returns true if for every '*' (star) in the string, if there are chars both immediately before and after the star, they are the same.

Given two strings, base and remove, return a version of the base string where all instances of the remove string have been removed (not...

Given a string, return true if the number of appearances of "is" anywhere in the string is equal to the number of appearances of "not"...

We'll say that a "triple" in a string is a char appearing three times in a row. Return the number of triples in the given string. The...

We'll say that a lowercase 'g' in a string is "happy" if there is another 'g' immediately to its left or right. Return true if all the...

Given a string, return the length of the largest "block" in the string. A block is a run of adjacent chars that are the same.

Given a string, look for a mirror image (backwards) string at both the beginning and end of the given string. In other words, zero or...
