In this problem, given a list of N intervals, we want to find the closest non-overlapping interval greater than each interval in the dataset. The function closest_interval takes in the list of intervals and return a list of indices corresponding to the index of the closest interval for each element in the list. If a particular interval does not have a closest non-overlapping interval in the given list, return 1 corresponding to that element in the list
