• ### Equilibrium Index#2 is the latest revision

Write a function: function solution(A); that, given a zero-indexed array A consisting of N integers, returns any of its equilibrium indices. The function should return −1 if no equilibrium index exists.

• ### Determine whether a triangle can be built from a given set of edges#26 is the latest revision

By sorting the array, we have guaranteed that P+R < Q and Q+R < P (because R is always the biggest). Now what remains, is the proof that P+Q > R, that can be found out by traversing the array. The chance to find such a combination is with three adjacent values as they provide the highest P and Q.

• ### What Split in Array Yields Min Value

Write a function that, given a non-empty zero-indexed array A of N integers, returns the minimal difference that can be achieved.

• ### Frog Jump Problem#14 is the latest revision

A small frog wants to get to the other side of the road. The frog is currently located at position X and wants to get to a position greater than or equal to Y. The small frog always jumps a fixed distance, D. Count the minimal number of jumps that the small frog must perform to reach its target.
