Give a simple, high$-$level three line description $($do this, do that, do this$)$ of an iterative method to modify L so that for each record r in the list, r$.$dat is changed to be r$.$dat plus all of the $.$dat values in the records that follow $($succeed$)$ r in the $($original$)$ list L$.$ So if the numbers in the list are $3,4,5,6,7,$ then they are changed to $25,22,18,13,7.$ Detailed pseudocode is unnecessary for this part. Does part ii make this easier? $($Your answer could be no$.)$
