• Collections, Map, Filter --> BinaryGap [Codility]

Arrays

• Modulo operator, rotating within a Range, Indicies --> CyclicRotation [Codility]
• Array loop range, Sort, Step 2 --> OddOccurrencesInArray [Codility]

Time Complexity

• Math, Ceiling --> FrogJmp [Codility]
• Ordered list permutation, Find missing, (n+1)*(n+2)/2 --> PermMissingElem [Codility]
• Max minimal difference among array elements --> TapeEquilibrium [Codility]

Counting Elements

• Hash Set, .withIndex, n * (n+1)/ 2 --> FrogRiverOne [Codility]
