Circles

Input

The first line contains one integer $n$ (1 \leq n \leq 10\,000). Each of the next $n$ lines contains three positive integers $x$, $y$, $r$ less than $10000$, which specify the coordinates of the circle center $(x,y)$ and its radius $r$.

Output

Print the pair of numbers of intersecting circles, or the number $0$ if no two circles intersect. The circles are numbered according to the order in the input file, starting from $1$ to $n$. If there are several pairs of intersecting circles, print any one of them. The elements of the pair can be printed in any order.
