What is the output of this Pseudocode?

Question

Hi, I need your help with this task:
Input: Array A with the length |A|=n of the natural numbers a in N ^ >=1
Output: Boolean value
x:= 0;
For i:= 1 to n do
x:= x + A[i];
End for
If x<2 then
Return false;
End if
For i:= 2 to x -1 do
If x mod i=0 then
Return false;
End if
End for
Return true;

1) Question: what is the output of the algorithm with input Array [2,3,5,7] ?

Is the output for 2 true?
For 3 false?
For 5 false?
For 7 false?

2) what does the algorithm in general?

Does it reduce the input in the loop and calculates if the mod is 0? So it is basically looking if the two numbers (one of them is reduced)are multiples of each other?

I would really appreciate your help!

Answer 1

ok changed the title. thanks for the remark.
Well, the question did not change. I kinda need help with solving this pseudocode so if anyone wants to help me with that, i would really appreciate it

Answer 2

Would anyone analyze the worst time complexity of this ?
