x,y=map(int,input().split())
for i in range(x+1,y+1):
    for j in range(x,i):
        print(x,end="")
    for j in range(i,y+1):
        print(j,end="")
    print()
count=2
for i in range(x,y-1):
    for j in range(x,y-count+1):
        print(j,end="")
    for j in range(count):
        print(y,end="")
    count+=1
    print()
