2)

rec(4) => if(4<=0) : false; thus print 4 and call rec(3)

rec(3) => if(3<=0) : false; thus print 3 and call rec(2)

rec(2) => if(2<=0) : false; thus print 2 and call rec(1)

rec(1) => if(1<=0) : false; thus print 1 and call rec(0)

rec(0) => if(0<=0) : true; thus return

Therefore the output will be : 4 3 2 1
