#Write a program that finds the maximal and minimal values among four 
#integeres. 


#input: 4 integers, num1, num2, num3, num4

#Example: num1=4 num2=3 num3=12 num4 = -15
#Output: max = 12 min = -15

#num1>num2 4>3 max=4 min=3
#max<num3 4<12 max=num3=12
#max<num4 12<-15 False max = 12

#Input
num1=int(input("enter first int "))
num2=int(input("enter second int "))
num3=int(input("enter third int "))
num4=int(input("enter fourth int "))


#Calculations
if(num1>num2):
	max=num1
	min=num2
else:
	max=num2
	min=num1

if(max<num3):
	max=num3

if(max<num4):
	max=num4

if(min>num3):
	min=num3
if(min>num4):
	min=num4

#Output
print("max=", max)
print("min=", min)
