The first line contains a single integer n (1 ≤ n ≤ 1000) that denotes number of fractions. Each of the next n lines contains two integers denoting the numerator and denominator of the fractions.
The numerators and denominators will be in the range .
Print n fractions in n lines in descending order. If two fractions are same, maintain the input order for printing.
Please refer to sample input/output section for better understanding.
