Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many power-delivery solutions. Yet sometimes a device has no direct power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.

清華大學數據結構課上實現的B+樹，設計一個4階B+樹，包括： (1) 葉子的每個記錄應該包括4字節（long）關鍵碼值和60字節的數據字段(存儲文件名等，可以自定)，設每個葉子可以存儲5條記錄，而內部節點應該是關鍵碼值/指針對。此外，每個節點還應該有指向同層下一個節點的指針、本節點存儲的關鍵碼數等； (2) 此4階B+樹應該支持插入、刪除以及根據給定關鍵碼值進行精確檢索與關鍵碼范圍檢索； (3) 顯示（打印）此4階B+樹的生長(含刪除節點)過程實例；

WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.
