**Problem Statement**

You are given an array arr of size n and an integer k. You need to find if there's a triplet in the array which sums up to the given integer k.

The function triple_sum© accepts the parameters array of integer arr having size n and an integer k.Complete the function triple_sum and return 1 if the triple sum exists else return 0.

For Example: if the array arr is [1,3,6,7,8,12,1] of size 7 and value of k is 18 then 3+7+8=18. the output will be 1.

**Problem Statement:**

A power jumper has the capability to increase his strength every time he takes a jump. When he takes consecutive jumps, he starts with a single unit distance jump and every next jump in the forward direction has t strength (i.e. distance) of his previous two jumps.

Every next jump in the backward direction has a strength (i.e. distance) of 1 unit.

If he turns his directions, he loses all his concentration and strength. He is standing at a lane having a wall at its start and end. If at an instant, he is at the start of the lane and starts jumping consecutively, how ma will it take for him to reach X units distance from the start?

Note: He can jump only backwards and forwards.
