[Topic] enter an array in ascending order, a given number, and search for two numbers in the array so that their sum is equal to the given number. The time complexity is O (n). If there are multiple matching numeric pairs, only one pair is given. For example, if the input array "1, 2, 4, 7, 11, 15" is given a number of 15, the output should be "4, 11 』.

PHP Statistical array of 10 occurrences of the most frequent number of methods
This article mainly introduces the PHP statistical array of 10 occurrences of the most frequent number of methods, involving PHP array_count_values and Arsort methods related to the use of skills, very practical value, the need for friends
The beauty of programming Reading Notes 10: 2.18 array Segmentation
If direct traversal is performed, at least Cr (n-1, 2 * n) times (Cr (m, n) are traversed to obtain the number of M combinations from N ), to reduce the number of traversal times, you can first sort the array. Then, all possible combinations are roughly divided into several groups. The arrays o
An array is a collection of values in a program that is stored by the same type, which exists in all programming languages. When declaring an array, you need to indicate the array type and the name of the array variable, the length of the arrays is immutable after initialization, and the elements in the
