Structure-01. Rational Number comparison (10)

This question requires programming to compare the two rational numbers.

Input Format:

Input two rational numbers in the form of scores in a row in the format of "A1/B1 A2/B2". The numerator and denominator are all positive integers in the Integer Range.

Output Format:

Output two rational numbers in a row in the format of "A1/B1 link character A2/B2. ">" Indicates "greater than", "<" indicates "less than", and "=" indicates "equal ".

Input Example 1:

1/2 3/4

Output Example 1:

1/2 < 3/4

Input Example 2:

6/8 3/4

Output Example 2:

6/8 = 3/4
