The problem of program design is a new type of question that arises in the middle school entrance examination in recent years. By setting a practical problem scenario, several solutions are given to let a candidate select the best solution through calculation or give a design requirement so that the candidate designs himself Program, due to more than one program, so these questions have the characteristics of open-ended questions. Program decision-making type of questions to examine the candidates awareness of mathematical applications, the proposition of a wide range of backgrounds, candidates have the freedom to display their talent in a large space, so much the proponent of all ages. First, the shopping case Example 1 Beginning of the beginning Xiaofang and Xiao Liang go to the school store to buy school supplies, small
