Question

equation "x=y", for example, "111-12", you need to add pluses inside x to make the equation correct. In our example "111=12", we can add one plus "11+1=12" and the equation becomes correct. You need to find the minimum number of pulses to add to x to make the equation correct. If there is no answer print -1. Note that the value of y won't exceed 5000. The numbers in the correct equation may contain arbitrary amount of leading zeros. coding in python​

Answer 1

Program:

x = int(input("Enter the value of x : "))

y = int(input("Enter the value of y : "))

if x == y and y <= 5000:

   print("The equation is correct")

elif x < y and y <= 5000:

   print("We need to add", (y - x),"to x to make the equation correct")

else:

   print("-1")

Output 1:

Enter the value of x : 11

Enter the value of y : 12

We need to add 1 to x to make the equation correct

Output 2:

Enter the value of x : 23

Enter the value of y : 23

The equation is correct

Output 3:

Enter the value of x : 23

Enter the value of y : 12
