Two programmers asked to write the code to evaluate the following expression:

a - b + c/(a-b) + (a-b)2

Pankaj writes the following code statements (Code A):

print (a-b) + c/(a-b) + (a-b)*(a-b)

Mythili writes the following code statements (Code B):

d = (a-b)

print d + c/d + d*d

If the time taken to load a value in a variable, for addition, multiplication or division

between two operands is same, which of the following is true?

Option 1 : Code A uses lesser memory and is slower than Code B

Option 2 : Code A uses lesser memory and is faster than Code B

Option 3 : Code An uses more memory and is faster than Code B

Option 4 : Code A uses more memory and is slower than Code B

Answer: Option 1
