European Space Agency has telescopes observing distant planets. They classified different types of events. They noticed that every day on each planet there is exactly one type of event. They measure events in days because they discovered each event lasts at least one day, and at most days. Events last only a complete number of days, they never last a fractional part of a day. Each event of the same type lasts exactly the same number of days every time it occurs, regardless of the planet it occurs on.
After many years of observation, they want to analyze data. The telescopes logged all observations, but unfortunately they forgot to write down the year the observations took place! Each telescope entry consists of the start date, end date and number of each type of event observed. Given all observations on all planets, calculate the duration of each type of event. Note that the telescopes are super precise and they start working exactly when the event starts and end when an event ends, not necessarily the same one.
Note: For this task, each year has exactly days.
Input Specification
First line contains integers and , the number of telescopes and the number of event types. Next lines contain numbers each:
""
Where are start date, end date, and number of times event type was observed.
Output Specification
One line containing numbers, durations of event types. If more than one solution exists, output any
one. If no solution exists, output -1
.

Explanation for Sample Output 1
The telescope observed one type 1 event between 26 February and 3 March. The only possible explanation is that type 1 events last 5 days.
