Thanks. Here's the first one(I was too lazy to translate the second one too, but I'll do it). It's quite easy, but the second one was hard.

Problem 1:
In a group of n persons, there are pairs of persons considered friends. Considering my friend's

friend is my friend, identify all the groups made by exactly k persons that are friends(directly or

indirectly).
Input datos:
-k is read from the keyboard
-there is a file called graph.txt that contains on the first line n(the number of persons), and on

the next lines are pairs of numbers which represents the friendship relations.
Output datos:
-the results should be written in the file group.txt
-on each line, there should be written a group of persons

Examples:
k=3
graph.txt
9
1 2
4 5
2 3
7 8
7 9
group.txt (this way it should look)
1 2 3
7 8 9

k=2
graph.txt
3
1 2
2 3
group.txt(it shouldn't contain anything)
