My code is not working on codeblocks but is working on online compiler.
It shows filename.exe has stopped working without taking any input
link to code :
hey you should declare bool ar[a+1] after scaning the value of a.
If you still have any problem feel free to comment.

I think it’s memory error because variable a holds some garbage value initially until it’s declared hence when u declare an array i.e bool ar[a+1] it exits due to failure of memory allocation. Try moving bool ar[a+1] below fastscan(a).
ohh my bad!!
thanks
Also in this code
All testcase works fine but for particulary this input it prints garbage value.
testcase :
9 10
1 2 3 4 5 6 7 8 9
1 5
5 6
6 7
5 7
9 1
1 2
2 8
2 3
3 4
2 4

I got this output by running your code-
value of node1
5 9 2
value of node2
1 8 3
value of node3
2 0
value of node4
0
value of node5
1 6 7
value of node6
5 7
value of node7
6 5
value of node8
2
value of node9
1
I cant see any garbage value here 
And what is the question? Debugging code without knowing the purpose of code is like shooting an arrow in dark.
Actually i figured out it was problem of using fastscan()
it was taking space as input when i was copying testcase .
