Investments in 2016
Tables: Insurance(pid INT, tiv_2015 FLOAT, tiv_2016 FLOAT, lat FLOAT, lon FLOAT). Insurance.pid is unique. tiv_2015 and tiv_2016 are investment amounts for their named years; lat and lon are non-null coordinates. Sum tiv_2016 for policies whose tiv_2015 occurs in at least one other policy and whose (lat, lon) pair occurs in no other policy. Apply both conditions and return the sum as tiv_2016 rounded to two decimals. Coordinate uniqueness concerns the pair, not each coordinate separately.
