DescriptionYou ' re given a list of n strings a1, a2, ..., an. You ' d like to concatenate them together in some order such that the resulting string would be lexicographically smallest.Given the list of strings, output the lexicographically smallest concatenation.InputThe first line contains integer n -the Number of strings (1≤ n ≤5 104).

Java entry (5) -- String/string class, entry String In the previous example, there was a String example. Some friends certainly didn't know what to do. In fact, the String class is a special class in Java, namely the String class.

Strings are the most widely used data types in programming. They are simple and practical, but understanding them in depth will bring us more benefits. String cache pool: To save memory and improve resource reuse, Java introduces the String cache pool concept. Strings in the cache Pool cannot be recycled: Strings in the cache pool will not be recycled by the garbage collection mechanism. They are basica

1. Stacks and heaps (heap) are places that Java uses to store data in RAM. Unlike C + +, Java automatically manages stacks and heaps, and programmers cannot directly set up stacks or heaps.2. The advantage of the stack is that the access speed is faster than the heap, second only to the registers directly in the CPU. However, the disadvantage is that the size and lifetime of the data in the stack must be deterministic and inflexible. In addition, the stack data can be shared, see 3rd. The advant

Let's consider a question about a string in Java: The difference between "abc" + "/" and "abc" + "/". With this example, we can practice the use of JAVAP in the JDK tool by the way, as the original question goes: What's the difference between a slash/a character or a string?One is as basic data type char and one is object string. What difference does it have?Is
