We are given n independent and indivisible jobs numbered from 1 to n. They should be executed sequentially in any order. The later the execution of a job starts the longer it lasts - precisely, the time of execution of the job i is h_i(t)=a_it+b_i, if we start it in the moment t. We assume that 0<=a_i<=1, 0<=b_i<=1.

The goal is to schedule the jobs so that the total execution time is the shortest.

Task

• reads from the text file SZE.IN the number of jobs n not greater than 10000 and successively - for each job i - the coefficients a_i and b_i determining the dependence of the job execution time upon the time it starts,
• finds such a scheduling of the jobs that the cumulative execution time is minimal; then the program writes to the file SZE.OUT the numbers of the jobs in the order they should be executed.

Input

• In the first line of the file SZE.IN there is one positive integer not greater then 1000. It is the number of jobs n.
• In each of the following n lines there is a pair of nonnegative real numbers. The numbers are written in a standard form with a decimal point and six digits after the point. The numbers are separated by a single space. It is the pair of coefficients a_i and b_i determining the dependence of the execution time of the corresponding i-th job upon the time it starts.
