You are given a two dimensional array containing arrays of intervals and an array K containing a single interval as arguments. Return true if all of the intervals in the inner arrays are enclosed in the single interval K, false if not.

Requirements

• Must return either true or false

Example #1

solve([[4,5],[6,7]], [3,8])
> true

The intervals 4 thru 7 are enclosed in the interval 3 thru 8 so we return true.

Example #2

solve([[2,5],[6,9]], [3,8])
> false

The intervals 2 thru 9 are not enclosed by the interval 3 thru 8 so we return false.
