The option that is the most appropriate documentation to appear with the swapListElements procedure is option B) Returns a copy of numList with the elements at indices j and k interchanged.The values of j and k must both be between 1 and LENGTH(numList), inclusive.
Documentation is essential for understanding how to use a function or procedure, and it should clearly communicate the purpose, input parameters, output, and any constraints or requirements.
So, option B accurately describes the behavior and constraints of the swapListElements procedure, it can be considered appropriate documentation for the procedure.
See text below
In the following procedure, the parameter numList is a list of numbers and the parameters j and k are integers.
PROCEDURE swapListElements(numList, j, k)
{
newList ←← numList
newList[j] ←← numList[k]
newList[k] ←← numList[j]
RETURN(newList)
}
Which of the following is the most appropriate documentation to appear with the swapListElements procedure?
A) Returns a copy of numList with the elements at indices j and k interchanged.The value of j must be between 0 and the value of k, inclusive.
B) Returns a copy of numList with the elements at indices j and k interchanged.The values of j and k must both be between 1 and LENGTH(numList), inclusive.
C) Interchanges the values of the parameters j and k.The value of j must be between 0 and the value of k, inclusive.
D) Interchanges the values of the parameters j and k.The values of j and k must both be between 1 and LENGTH(numList), inclusive.
