C++ algorithm: shortest string containing three strings
Involving knowledge points Sorted set string Title You are given three strings a, b and c. Your task is to find the string with the shortest length, and these three strings are all its substrings. If there are multiple such strings, please return the one with the smallest lexicographic order. Please return a string that […]
Solution to the mismatch between the field name in the JSON string and the field name in the Java class (use of @JsonProperty(“”) and @JSONField(name = “”))
1.1 Background 1.1.1 The so-called background, that is, what is the purpose and reason for writing this blog? Recently, I encountered a very strange requirement at work. I used WebService to adjust a third-party interface, but the return value of the third-party interface was an Xml structure. It was not surprising at first. But then […]
Data Structure (C Language) Experiment-Stack and String
Delete substring The string is stored in a linked list with the leading node, and the algorithm function void delstring(linkstring s, int i, int len) is designed. Delete the substring starting from the i-th position and having a length of len in the string s. void delstring(linkstring s, int i, int len) { linkstring p,q,r; […]
Filling the hole: Java’s String class (1)
Common methods String construction Let’s take a look at the String construction method in the source code Common string //”hello” is a string constant, without \0 mark at the end String str = “hello”; System.out.println(str);//hello String str2 = new String(); System.out.println(str2);//No output String str3 = new String(“pppp”); System.out.println(str3);//pppp String array char[] array = {‘a’,’b’,’c’}; String […]
