##Array checker
- Array of integers is given
- x is a number from the array
- We jump x positions in the array from current positions either forward or backward; if that position is not visited we repeat this jump sequence unless all the positions on array are covered; else we move to next x number in the array.
- If all the array positions are covered by that x without violeting the condition, then we store that x in answer table.
- This answer table is the output
