In Julia, you can delete an element from an array using the splice! function.
The splice! function takes three arguments: the array to modify, the start index of the elements to remove, and the number of elements to remove.
Here's an example:
# Define an array
array = [1, 2, 3, 4, 5]
# Remove the element at index 3
splice!(array, 3, 1)
# Print the modified array
println(array) # Output: [1, 2, 4, 5]
In this example, we defined an array [1, 2, 3, 4, 5]. We used the splice! function to remove the element at index 3 by specifying the array to modify (array), the start index of the element to remove (3), and the number of elements to remove (1).
After calling splice!, the modified array will be [1, 2, 4, 5].
You can also use the deleteat! function to remove elements from an array based on given indices. Here's an example:
# Define an array
array = [1, 2, 3, 4, 5]
# Remove elements at index 2 and 4
deleteat!(array, [2, 4])
# Print the modified array
println(array) # Output: [1, 3, 5]
In this example, we defined an array [1, 2, 3, 4, 5]. We used the deleteat! function to remove the elements at index 2 and 4 by specifying the array to modify (array) and the indices of the elements to remove ([2, 4]).
After calling deleteat!, the modified array will be [1, 3, 5].
