HDOJHDU 1015 Safecracker(深搜)
Problem Description === Op tech briefing, 2002/11/02 06:42 CST === “The item is locked in a Klein safe behind a painting in the second-floor library. Klein safes are extremely rare; most of them, along with Klein and his factory, were destroyed in World War II. Fortunately old Brumbaugh from research knew Klein’s secrets and wrote them down before he died. A Klein safe has two distinguishing features: a combination lock that uses letters instead of numbers, and an engraved quotation on the door. A Klein quotation always contains between five and twelve distinct uppercase letters, usually at the beginning of sentences, and mentions one or more numbers. Five of the uppercase letters form the combination that opens the safe. By combining the digits from all the numbers in the appropriate way you get a numeric target. (The details of constructing the target number are classified.) To find the combination you must select five letters v, w, x, y, and z that satisfy the following equation, where each letter is replaced by its ordinal position in the alphabet (A=1, B=2, …, Z=26). The combination is then vwxyz. If there is more than one solution then the combination is the one that is lexicographically greatest, i.e., the one that would appear last in a dictionary.”

，尝试一个密码最多4秒钟，但这样以来效率也仅仅是减少了1/3；之后Seidle 发现了一个技巧，他利用保险柜本身的设计缺陷，在设置的密码凹槽会比其他凹槽窄一些，而这个差别是肉眼无法感觉得到的，之后让Safecracker
