In celebration of the 4th of July, Aldo goes to an American buffet. In this buffet, there are different types of dishes. The -th plate fills a percentage of your stomach and gives you a percentage of happiness.

Aldo can eat a plate at the most once, because he wants variety, and he wants to achieve 100% happiness without going over 100% full. Help Aldo determine the maximum number of dishes he can eat while satisfying his restrictions.

Notes:

It is valid to exceed 100% happiness, but not 100% fullness. It is guaranteed that Aldo can always reach 100% happiness.

Input : The first line contains an integer, the number of dishes. The following lines contain 2 integers each, and the percentages of fullness and happiness that they cause, respectively.

Example input :

  • 3
  • 60 50
  • 30 50
  • 50 60
  • Answer : 2
  • 2
  • 100 20
  • 100 100

Answer : 1
