Answer:
function sum(number) {
if (number == 1) {
return 1;
}
return number + sum(number -1);
}
Explanation:
This is a recursive function, it means that is a function that calls itself for example: if you call the function with sum(5) the process is :
sum(5)
|______ 5 + sum(4)
|_______ 4 + sum(3)
|______ 3 + sum(2)
|_____2 + sum(1)
|_____ 1
the result is 1+2+3+4+5 = 15
Answer:
Option (4) is the correct answer.
Explanation:
In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".
But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--
a.add(element); //where add is a function, element is a value and a is a array list object.
Another option is invalid because--
- Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
- Option 2 gives a compile-time error because add functions bracts are not closed.
- Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.
