Description: /*
功能:
输入参数：int*p 指向二维数组的首地址，该二维数组第0行的两个数分别表示：总钱数<30000，和希望购买物品的个数<25
该数组从第1行到第m行(1<=j<=m)中给出了编号为j的物品的基本数据，每行有2个非负整数，
表示该物品的价格(<=10000)和该物品的重要度(1~5)。
GetResult表示不超过总钱数的物品的价格与重要度乘积的总和的最大值(<100000000)。
不需做入参检查，测试用例可以保证～
例如：4000 8（第0行）
821 3 （第1行）
422 5
458 5
500 3
200 2
430 4
530 3
239 3
则表示 总钱数为4000，希望购买物品个数为8个，因此从第1行到第8行表示编号为j的物品的价格及物品的重要度。
返回值：无

Description: RS-232、RS-485和S-422的区别
1、RS-232-C
RS-232-C是美国电子工业协会EIA（Electronic Industry Association）制定的一种串行物理接口标准。RS是英文“推荐标准”的缩写，232为标识号，C表示修改次数。RS-232-C总线标准设有25条信号线，包括一个主通道和一个辅助通道。 -RS-232, RS-485 and RS-422 difference 1, RS-232-C RS-232-C serial physical interface is a standard Electronic Industries Association EIA (Electronic Industry Association) to develop. RS is in English "recommended standard" abbreviation for the identification number 232, C represents the number of changes. RS-232-C bus standard has 25 signal lines, including a main channel and a secondary channel.

Description: ISO3080和ISO3086是隔离的全双工差分线路驱动器和接收器，而ISO3082和ISO3088是隔离的半双工差分线路收发器，器件符合TIA/EIA485/422应用标准。
这些器件非常适用于长输电线路由于接地环路断开，以允许大得多的共模电压范围。该装置的对称的隔离屏障进行了测试，以提供60秒2500Vrms的隔离的总线线路收发器和逻辑电平的接口。噪声瞬变可能会损坏所述收发器和/或接近的敏感电路，如果他们具有足够的强度和持续时间的话。这些分离装置可以显著提高保护和减少对昂贵的控制电路造成损坏的风险。
TheISO3080，SO3082，ISO3086 and ISO3088可使用温度范围为-40°C到85°C。-The ISO3080, and ISO3086 are isolated full-duplex differential line drivers and receivers while the ISO3082, and ISO3088 are isolated half-duplex differential line transceivers for TIA/EIA485/422applications.
These devices are ideal for long transmission lines since the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 2500 Vrms of isolation for 60s between the bus-line transceiver and the logic-level interface. Any cabled I/O can be subjected to electrical noise transients various sources.These noise transients can cause damage to the transceiver and/or near-by sensitive circuitry if they are of sufficient magnitude and duration. These isolated devices can significantly increase protection and reduce the risk of damage to expensive control circuits.
TheISO3080, SO3082,ISO3086 andISO3088 are qualified for use –40°Cto 85°C.

Description: Modbus通讯协议
Modbus协议最初由Modicon公司开发出来，在1979年末该公司成为施耐德自动化(Schneider Automation)部门的一部分，现在Modbus已经是工业领域全球最流行的协议。此协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备，包括PLC，DCS，智能仪表等都在使用Modbus协议作为他们之间的通讯标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中监控。
