Answer 1

Answer:

#program that accepts three number and swaps those number first and second,second and third

a=int(input("Enter the first number :"))

b=int(input("Enter the second number :"))

c=int(input("Enter the third number :"))

print("numbers before swaping of first and second number :",a,b)

a=a+b

b=a-b

a=a-b

print("numbers after swaping of first and second number :",a,b)

print("numbers before swaping of second and third number :",b,c)

b=b+c

c=b-c

b=b-c

print("numbers after swaping of second and third number :",b,c)

Answer 2

a=int(input("enter the first value "))

b=int(input("enter the second value"))

c=int(input("enter the third value"))

a=a+b

b=a-b

a=a-b

print(a,b)

b=c+b

c=b-c

b=b-c
