Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

Question

Answer the questions:

Which of the following recursive methods performs the same behavior as the following iterative code?
public static int iterativeSum(int sumBy, int sumTimes) {
int result = 0;
for (int i = 0; i < sumTimes; i++) {
result += sumBy;
}
}
return result;
public static int recursive Sum(int sumBy, int sumTimes) {
if (sumTimes <= 0) {
return 0;
}
}
public static int recursive Sum(int sumBy, int sumTimes) {
if (sumTimes <= 0) {
} else {
return sumBy + recursive Sum (sumBy, sumTimes - 1);
}
}
}
} else {
return sumBy + recursive Sum (sumBy, sumTimes - 1);
}
public static int recursiveSum(int sumBy, int sumTimes) {
if (sumTimes <= 0) {
return sumBy;
return sumBy * sumTimes;
} else {
return sumBy + recursive Sum (sumTimes - 1, sumBy);
}
public static int recursive Sum (int sumBy, int sumTimes) {
if (sumTimes == sumBy) {
return sumBy;
} else {
return sumBy + recursive Sum (sumBy, sumTimes - 1);
}

Question 3
Please select which of the following statements is FALSE about recursion
All iterative code can be written recursively and vise versa
Recursive methods are treated by Java the same as all other methods, there is no special code to trigger
recursion
Recursive methods must have exactly one base case and one recursive case
A recursive method instance cannot access the state of the parameters of other instances of that
recursive method; all data must be shared via parameters and returns.
