An vector 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 vector indexed by   j . this new value should be equal to twice the value stored in the next element of the vector (i. e. the element after the element indexed by   j ).  do not modify any other elements of the vector!

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
