// Take 2 arrays that contain times and outer bounds
// compare to find times that are available in both arrays within outer bounds
// return array with times meetings could take place
// data is valid and ordered

// P - Plan
// python - range?
// go thru first arr,
// compare arr[1] to arr[0] of next sub array
// add difference to new array
// do same for 2nd array
// if they both fit
// add to output
