With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: It is extremely challenging to count the number of steps of an algorithm on all possible inputs. As the complexity generally increases with the size of the input, the complexity is typically expressed as a function of the size (in bits) of the input, and therefore, the complexity is a function of. However, the complexity of an algorithm may vary dramatically for different inputs of the same size. Therefore, several complexity functions are commonly used.
text_B: Is the complexity of an algorithm dependent on the input?
YES.
