The first line of this file is the header of the three columns mentioned above respectively. $$ Here is a sample from the file:transactions$\_$Products.csvProduct$\_$ID$,$Product$\_$Name,PriceP$1,2-$in$-1$ Laptop,$1500$P$2,$Game Laptop,$2000$P$3,$Titan Laptop,$2100$ Each time a customer comes to the store they can haggle and obtain a special discount.The store keeps another file called$$transactions$\_$Sales.csv$$to record transactions. Each line in this file consists of the transaction ID$,$ a date for the transaction, a product ID$,$ the number of items, and the obtained percentage of discount after haggling, all separated by a comma. The first line of this file is the header of these five columns.
