1, from a macroscopic point of view, the four trees as four particlesThe first approach is to plant them together so that the distance between 22 is 0;The second option is to make them form a triangular pyramid, such as a tree at the top of the hill, a three-bearing tree at the foot of the mountain, or a tree at the bottom of the pit, with three trees planted outside the pit.2, from the microscopic point of view, the four trees are shape, then the focus lies in their "distance" how to define.Fir

Str1.equals (str2) to judge, cannot use = or! = To determine the reason:
Because string is of the reference type rather than the basic data type, their comparison uses the address and value (equivalent to the pointer in C) for comparison, because they are different objects, there are different addresses, so str1! = Str2 is always true. Str1 = str2 is always false. Use str1.equals (str2) If you want to compare their values ). Use = or! = Is the comparison of objects, they are true condition: no

http://www.51nod.com/onlineJudge/questionCode.html#!problemId=1393The method is fascinating. Also looked at other people's thinking to come out.First consider turning 0 all into-1. Then a prefix is counted and expressed in sum[i].Then the substring starting from the starting point is valid as long as the value of Sum[i] equals 0.If the substring starting point is not 0, then as long as two occurrences of sum[i], the two values must be a valid substring.For example:Label: 1 2 3 4 5Value 0 0 1 1 0
