Given an array of ints, return true if the value 3 appears in the array exactly 3 times, and no 3s are next to each other.

Given an array of ints, return true if every 2 that appears in the array is next to another 2. Otherwise, return false.

Given a non-empty array, return true if there is a place to split the array so that the sum of the numbers on one side is equal to the...

Consider the leftmost and righmost appearances of some value in an array. We'll say that the span is the number of elements between the...

Return an array that contains exactly the same numbers as the given array but re-arranged so that every 3 is immediately followed by a 4....

We'll say that a "mirror" section in an array is a group of contiguous elements such that somewhere in the array, the same group appears...

Write a function in Java that implements the following logic: Return a version of the given array where each zero value in the array is...

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

Given an array of int values, return true if the group of n numbers at the start of the array is the same as the group of n numbers at...

Say that a "clump" in an array is a series of 2 or more adjacent elements of the same value. Return the number of clumps in the given...

Given an array, return an array that contains exactly the same numbers as the original array, but rearranged so that every 4 is...

Return an array that contains the exact same numbers as the given array, but rearranged so that all the even numbers come before all the...

Given n >= 0, create an array with the pattern {1, 1, 2, 1, 2, 3, ... 1, 2, 3 .. n} (spaces added to show the grouping). Note that...

Given a string of any length, return a new string where the last 2 chars, if present, are swapped, so "coding" yields "codign".

Return true if somewhere in the array, there are three increasing adjacent numbers like .... 4, 5, 6, ... or 23, 24, 25.

Given start and end integers, return a new array containing the sequence of integers from start up to but not including end, so start = 5...

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 an array of ints, compute recursively the number of times that the value 11 appears in the array (no loops). We'll use the...

Given an array of ints, compute recursively if the array contains somewhere a value followed immediately by that same value times 10....

Given an array of ints, compute recursively if the array contains a 6. We'll use the convention of considering only the part of the array...
