Create a function that will convert gross salary to net salary in an imaginary country. Name the function `convert_gross_to_net(salary)`

. The function should print the following information:

Your salary gross: {x}
Salary after social contribution: {y}
Net salary after tax: {z}

First, create two helper functions: `calculate_social_contribution(amount)`

and `calculate_tax(amount)`

, and use them later in your main function.

The `calculate_social_contribution(amount)`

function returns:

`0`

for amounts below 200.
`100`

for amounts greater than 200 and less than 1000.
`200`

for amounts greater than or equal 1000.

The `calculate_tax(amount)`

function should return the tax, which equals:

- 10% of
`amount`

if the amount is up to 3000.
`300`

+ 20% of all the amount above `3000`

if amount is greater than 3000.

Then, finally write the `convert_gross_to_net(salary)`

function. The function should print the following information:

Your salary gross: {x}
Salary after social contribution: {y}
Net salary after tax: {z}

The following rules apply:

First, the social contribution is calculated. Once the social contribution has been deducted from the salary, you need to calculate and subtract the tax from the remaining amount. Use the helper functions to do it.

For instance, for salary = 500:
