Problem:Write a function to find the longest common prefix string amongst an array of strings.Solution:time complexity O (n)Main topic:give a string array to find the maximum prefix common substring of these strings. Problem Solving Ideas:since it is a common substring, that each string must contain, and in the head, first the first string as the default maximum, and then followed by each string in contrast, calculate all the maximum matching length, the smallest is the lengthJava source code (s

-point method to determine the position of the elements, the exact sort of the back when there is no need for a great move, so to achieve high efficiency. For example: for a[] ={63, 4, 24, 1, 3, 15}, first we use the start step steps =length/2=3 each element in the array, and so on, exchange, that is to say, a[0] compared to a[0+step=3, a[0]>a[3] swap position, A [0]=1,a[3]=63 (in this case, 1 jumped to the first place), and then proceed to the next group of comparison A[1]>a[4] (subscript are d

In recent days, I have seen many questions about communication between C/C ++ and Java on csdn, especially the data structures (such as struct) Unique to C ). I would like to give an example based on a netizen's question, hoping to help beginners. Original problem see: http://community.csdn.net/Expert/topic/3886/388698

There is a Boolean data type in Java, True is true and False is false. Also, only Boolean values can be placed in the if () brackets.C's basic data types are basically consistent with Java, but C has more pointer types. Pointers are the focus of the C language.It is important to note that

functions such as the keyword starting with S. It is easy to set the value of auto activation triggers for Java, and change the original trigger "." To "." + 26 × 2 letters. Hmm? Why is it 26 × 2? Because the letters are case-sensitive, 26 in upper case and 26 in lower case. Of course 26 × 2 is the case! The procedure is as follows: Go to: Windows → preferences → Java → editor → content assist Then mo
