Interactive Brokers TWS may represent a signed quantity or price adjustment as a single integer. Write a function that classifies the value: return 1 for a positive integer, 0 for zero, and -1 for a negative integer.
Implement classify_sign(value), which accepts one integer value and returns one integer from {-1, 0, 1}. The result must indicate only the sign of the input, not its magnitude.
Do not convert the value to a string or use a library sign function. Use direct numeric comparisons so the behavior is explicit.
value is an integer.-10^9 <= value <= 10^9.-1, 0, or 1.def classify_sign(value):
