Modify the following program to the specifications given below:

Add a new status – SingleParent – where the tax is computed as a SINGLE but with a further reduction of $5000 per child.

Add a new tax condition – if the income is greater than $249,999 for SINGLE, then add a tax of 25% on income amount above $150,000; if the income is greater than $349,999 for MARRIED, then add a tax of 35% on income amount above $200,000.

Unknown status – if the status doesn’t belong to SINGLE or MARRIED or SINGLE_PARENT, then compute a 33% tax on the income.
