Time complexity measures the execution time of an algorithm relative to the size of the input. Tips for reducing the time complexity of C++ programs include: choosing appropriate containers (such as vector, list) to optimize data storage and management. Utilize efficient algorithms such as quick sort to reduce computation time. Eliminate multiple operations to reduce double counting. Use conditional branches to avoid unnecessary calculations. Optimize linear search by using faster algorithms such as binary search.

Recently, the industry has generally paid great attention to the application of PHP software suites in Linux operating systems. As today's most popular server-side scripting language, PHP has a wide range of applications in the field of Web development. The Linux system has become the first choice for the majority of users due to its stable performance, high security and complete openness. This article aims to discuss in detail the actual application of the PHP software suite in the Linux system environment and its maximum integration effect. 1. Introduction to PHP suite The so-called PHP suite is essentially a comprehensive tool component that facilitates programmers to easily complete related program tasks, reduces the complexity of code development, and thereby improves development efficiency.

The hash table can be used to optimize PHP array intersection and union calculations, reducing the time complexity from O(n*m) to O(n+m). The specific steps are as follows: Use a hash table to map the elements of the first array to a Boolean value to quickly find whether the element in the second array exists and improve the efficiency of intersection calculation. Use a hash table to mark the elements of the first array as existing, and then add the elements of the second array one by one, ignoring existing elements to improve the efficiency of union calculations.
