Input : a = 806, b = 91
Output : 80691

Input : a = 5, b = 1091
Output : 51091

Method 1: One method of achieving this can be counting the number of digits of second number. Then multiply the first number with 10^digits and adding both the numbers. Below is the implementation.






# Python program to concatenate
# two numbers
  
  
def numConcat(num1, num2):
  
     # find number of digits in num2
     digits = len(str(num2))
  
     # add zeroes to the end of num1
     num1 = num1 * (10**digits)
  
     # add num2 to num1
     num1 += num2
  
     return num1
  
  
# Driver's code
a = 906
b = 91
print(numConcat(a, b))
Output:
90691

Method 2: Another method can be converting both the numbers to the string. Then concatenate them and convert them back to integers. Below is the implementation.




# Python program to concatenate
# two numbers
  
  
def numConcat(num1, num2):
       
        # Convert both the numbers to
        # strings
        num1 = str(num1)
        num2 = str(num2)
          
        # Concatenate the strings
        num1 += num2
          
        return int(num1)
  
  
# Driver's code
a = 906
b = 91
print(numConcat(a, b))

Output:

90691
