Program to find sum of first and last digit of a given number.

Algorithm
Step 1: Read a number, num
Step 2: Compute num1=num%10
Step 3: Assign num2=num1
Step 4: Repeat step 5 while num2=>10
Step 5: Compute num2=num2/10

Step 6: print num1+num2

Step 7: Stop

Flowchart:

Program code: 

num=int(input('Enter a number '))
num1=num%10;
num2=num
while num2>=10:
    num2=num2/10;
print num1+num2
