 Google will only consider a candidate with poor communication ability if the candidate has a 'brilliant' innovation capability.
 
 Write a program that will help Google to programmatically determine eligibility of the fifteen candidates for these positions, and print the output on the console.

+9. Write a program that iterates through numbers from 0 to 113 using a loop.
+Print the numbers, one number per line.
+As you print each number, say x, also print the following when appropriate, separated by commas:
+
+If the number is odd, print “x is odd”
+If the number is divisible by 5, print “hi five”
+If the total of a number (x) and its subsequent number (x+1) is a value divisible by 7, print “wow”
+If the number is prime, print “prime”.
+
+10. 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.
