Amcat-python and c Programming and Technical Programming

The program accepts an integer N as the input. All the digits in the number must be repeated consecutively. If a digit is not repeated consecutively, the program must repeat it for two times. Finally, the program must print the modified integer value.

Boundary Condition(s):
1 <= N <= 10^13

Input Format:
The first line contains the value of N.

Output Format:
The first line contains the modified integer value.

Example Input/Output 1:
Input:
1223

Output:
112233

Explanation:
1 and 3 are not repeated consecutively. So consider 1 and 3 as 11 and 33.
Hence the output is 112233.

Example Input/Output 2:
Input:
998888745551

Output:
998888774455511
