### Instructions: You are an expert Python programmer. You will be given a question (problem specification) and will generate a correct Python program that matches the specification and passes all tests. You will NOT return anything except for the program.
### Question:
Given a positive integer N, print a string of N zeros and N+1 ones where 0 and 1 alternate.

Input

The input is given from Standard Input in the following format:
N

Output

Print the answer.

Constraints


- N is an integer.
- 1 \leq N \leq 100

Sample Input 1

4

Sample Output 1

101010101

A string of four zeros and five ones where 0 and 1 alternate is 101010101.

Sample Input 2

1

Sample Output 2

101

Sample Input 3

10

Sample Output 3

101010101010101010101

### Format: Read the inputs from stdin solve the problem and write the answer to stdout (do not directly test on the sample inputs). Enclose your code within delimiters as follows.
```python
# YOUR CODE HERE
```

### Answer: (use the provided format with backticks)
