Slice is a common data structure in Go language. It can be regarded as an abstraction of array. Slices have more flexible operations than arrays, one of which is deleting elements. This article will introduce how to implement slice deletion operation in golang.
- Introduction
In golang, slice is a dynamic array, which has strong scalability and flexibility and is one of the commonly used data structures in golang. . Slices can add elements at the end through the append() function, but golang does not provide a method to directly delete an element in the slice, so other methods need to be used.
- How to implement slicing to delete elements
2.1 Moving slicing elements
One way to slice and delete elements is to move the elements after the elements that need to be deleted The whole moves forward, covering the deleted elements. We can achieve the purpose of deleting elements by moving the elements behind the element that needs to be deleted forward one by one through a loop.
The following is a sample code for deletion by moving slice elements:
func remove(slice []int, elem int) []int { for i := 0; i <p>In the above code, we first traverse the entire slice, find the elements that need to be deleted through the if statement, and use copy() The function moves the elements after the element that needs to be deleted as a whole forward, and finally reduces the length of the slice by 1 through the slice copy operation, thereby realizing the deletion of the slice elements. </p><p>2.2 Slice element exchange</p><p>Slice element exchange is also a way to achieve slice deletion. Different from slice element movement, it will exchange the position of the element to be deleted with the last element. Then reduce the slice length by 1 to avoid the time or space loss that may be caused by element movement. The following is a sample code: </p><pre class="brush:php;toolbar:false">func remove(slice []int, elem int) []int { for i := 0; i <p>In the above code, we also traverse the entire slice, find the element that needs to be deleted through the if statement, exchange the position of the element that needs to be deleted with the last element, and then reduce the length of the slice by 1 , realizes the deletion of slice elements. </p><ol start="3"><li>Summary</li></ol><p> Slicing is a common data structure in Golang and has high scalability and flexibility. In golang, slicing does not provide a method to directly delete an element, so other methods need to be used. This article introduces two implementation methods: slice element movement and slice element exchange. Readers can choose the appropriate method to implement slice deletion based on their specific needs. </p>
