Input
The first line contains an integer n (1?≤?n?≤?105) — the number of laptops.
Next n lines contain two integers each, ai and bi (1?≤?ai,?bi?≤?n), where ai is the price of the i-th laptop, and bi is the number that represents the quality of the i-th laptop (the larger the number is, the higher is the quality).
All ai are distinct. All bi are distinct.
