inline deduplication

Display:inline; Inline elements, in simple terms, are displayed on the same line.Display:block; A block-level element, which simply means that there is a newline and will be changed to the second line.Display:inline-block; is the block-level element within the same row.The default is inline, so inline is useless here. The wide height setting is also obsolete.bloc

Inline functions with the parameter macro definition and the inline decoration are replaced by the function body with a macro call or function call at compile time. The benefit of this is to reduce the time it takes to call the function.For example:Introduction to the algorithm when it comes to heap ordering, the good heap sort implementation is generally to leave (i), right (i), the implementation of the P

The group by statement can deduplicate a column.Directly run the preceding statement: select io_dev_id from io_info where (TID = 1 AND host_name = 'yang1') group by 1; deduplication BY io_dev_id. P: The difference between order by and distinct is that group by is used to select order by Based on the column. distinct is similar to group by, but it can only be placed behind select, the front of the filtered field. For example, select distinct a, B, c fr

The array_unique () function of PHP allows you to pass an array, remove duplicate values, and return an array with unique values, this article describes how to implement PHP array de-duplication quickly. For more information, see this article. The array_unique () function of PHP allows you to pass an array, remove duplicate values, and return an array with unique values. This function works well in most cases. However, if you try to use the array_unique () function in a large array, it will ru

This article mainly introduces the php two-dimensional array merging and deduplication methods. The example analyzes the php techniques for merging arrays and deleting repeated items, for more information about how to merge and deduplicate two-dimensional php arrays, see the example in this article. Share it with you for your reference. The specific implementation method is as follows: $ Arr = array_merge ($ labels, $ label); // merge the two arr
