```py
print("this is program is to check which NUMBER you chose is bigger,(NOTE: any input except number input     will break down the program)\n")
a=int(input("first number:")) 
b=int(input("second number:"))
c=int(input("third number:"))
if "a">"b":
    z=a
else:
    z=b
if "z" > "c":
    print(z)
else:
    print(c)

```
