Meaning of question A Give you a string and let you calculate how many pairs of adjacent letters there are, For example, a and b, b and c are two pairs of adjacent letters, while a and c, a and z are not. (Note: the letters on any two subscripts can become adjacent pairs. For example, for the string "adfb", the character 'a' with sub ...

1 load balancing algorithm The English name of Load Balance is Load Balance, which means to balance the load (work task) and allocate it to multiple operating units for operation, such as FTP server, Web server, enterprise core application server and other main task servers, so as to complete the work task together. Since it involves mul ...

preface We all know that there are five commonly used classical algorithms: divide and conquer algorithm, greedy algorithm, dynamic programming algorithm, backtracking algorithm, branch and bound algorithm. Each algorithm plays a very important role in computer science; This article will introduce an implementation of the divide and conquer al ...
