DISTX - Distance |
In this task let's consider distance between two positive integers defined as below.
Single operation is: multiplying some number by prime number or dividing some number by prime number (we can divide only when remainder is equal to 0.)
Distance d between two numbers a, b is minimum number operations to convert one number to another.
For example d(69, 42) = 3.
This distance is very similar to well-known term "distance" in real human life:
- d(a, a) = 0, distance number to itself is 0.
- d(a, b) = d(b, a) distance from a→b is equal to b→a.
- d(a, b) + d(b, c) ≥ d(a, c) triangle equation is true too.
With given n number you have to determine for each i-th of those numbers closest number aj from set that i ≠ j and if there is many numbers with equal, smallest distance, you have to pick number with smallest index
Input
In first line - number n ≤ 105.
In next n lines - i-th number. Every number is not greater than 106.
Output
You have to output n lines.
I-th line should contain index of closest number (if there are many answers, please output smallest index.)
Example
Input: 6

yup, you are right. |

The triangle inequality in the description should be using a >= rather than a >. |

Sorry, was translating it in night, now it's corrected. |

The range of N & the numbers? Edit: I've found the original problem. It states n<=10^5, each of the numbers <= 10^6. Last edit: 2011-11-15 11:01:07 |
