设有n个件工作分配给n个人。将工作i分配给第j个人所学要的费用为Cij。试设计一个算法，为每个人都分配1件工作，并使总费用达到最小-With n-pieces of work assigned to the n individuals. Will be allocated to the first j of work i personally have learned to cost Cij. Try to design an algorithm for each person assigned a work, and to minimize the total cost of

       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

c++的bit模板只能用常数制定大小，这里重新定义bit使其可以用变量第一定义大小，更方便

已知有n中货币c1,c2,c3...cn和有关兑换率的n*n的表R，其中Ri，j是一个单位的货币ci可以卖到的货币cj的数量，要求一个序列使之兑换结果变多。 

摸索了些，关键是几个参数自己一定要选对，否则测量精度大打折扣，定位的时候发现3个节点定位。 ，和n，y位为小数，所以要做相应处理（整数要左移两位） 值要再处理一下。
