# The function is expected to return a STRING.

# The function accepts following parameters:

# 1. INTEGER a

# 2. INTEGER b

# 3. INTEGER c

# 4. INTEGER d

Consider a pair of integers, (a, b). The following operations can be performed on (a, b) in any order, zero or more times: (a, b) = (a + b, b) (a, b) (a, a + b) Return a string that denotes whether or not (a, b) can be converted to to (c, d) by by performing zero or more of the operations specified above
