# 打印图案1
for i in range(5):
    for j in range(i+1):
        print("*", end="")
    print()

# 打印图案2
for i in range(5):
    for j in range(5-i):
        print("*", end="")
    print()

# 打印图案3
for i in range(5):
    for j in range(5-i-1):
        print(" ", end="")
    for k in range(2*i+1):
        print("*", end="")
    print()
