An array of int named a that contains exactly five elements has already been declared and initialized. in addition, an int variable j has also been declared and initialized to a value somewhere between 0 and 3. write a single statement that assigns a new value to the element of the array indexed by j. this new value should be equal to twice the value stored in the next element of the array (i. e. the element after the element indexed by j). do not modify any other elements of the array!
