Your task is to find all the elements of an array that are non consecutive. A number is considered non consecutive if it is not exactly one larger than the previous element in the array. The first element always gets a pass.

You should return the results as an array of objects with two values i: and n: .

Example

For the the array [1,2,3,4,6,7,8,10], the result should be:

nconsecutive([1,2,3,4,6,7,8,10])
[
  {'i': 4, 'n': 6},
  {'i': 7, 'n': 15}
]

Tests

[6,7,8,9,11,12]
[100,101,102,112,113,114,129]

Good luck!
