Equivalence partitioning involves dividing input data into partitions that are treated the same by the system under test. The given specifications create overlapping partitions:
* For n<0n < 0n<0, an error message "Value out of range" is issued.
* For 0<n<1000 < n < 1000<n<100, the factorial is calculated.
* For 100<n<200100 < n < 200100<n<200, the same error message "Value out of range" is issued.
However, the range between 0 and 100 is exclusive of 0 and 100, meaning that the partitions overlap and create ambiguity for the boundary values. Thus, the correct statement is that the requirements are not correct because the partitions are overlapping.
