def combinations(arr,data,start,end,index,r):

if index==r:

for j in range(r):

print(data[j],end=" ")

print()

return ;

i=start

while (i<=end and end-i+1>=r-index):

data[index]=arr[i]

combinations(arr,data,i+1,end,index+1,r)

i+=1

n=int(input())

l=list(map(int,input().split()))

printcmb(l,n,12)
