Solution 1: Using the push! function
To append a string to an array in Julia, you can use the push! function. This function modifies the array in-place by adding the specified element at the end.
array = ["apple", "banana", "orange"]
push!(array, "grape")
println(array)
The output of the above code will be:
[“apple”, “banana”, “orange”, “grape”]
Solution 2: Using the append! function
Another way to append a string to an array in Julia is by using the append! function. This function works similarly to push!, but it can append multiple elements at once.
array = ["apple", "banana", "orange"]
append!(array, ["grape", "kiwi"])
println(array)
The output of the above code will be:
[“apple”, “banana”, “orange”, “grape”, “kiwi”]
Solution 3: Using the pushfirst! function
If you want to append a string to the beginning of an array, you can use the pushfirst! function. This function adds the specified element at the beginning of the array.
array = ["apple", "banana", "orange"]
pushfirst!(array, "grape")
println(array)
The output of the above code will be:
[“grape”, “apple”, “banana”, “orange”]
Among the three options, the best solution depends on your specific use case. If you want to append a single element at the end of the array, using push! is the simplest and most straightforward option. If you need to append multiple elements at once, append! is a better choice. Finally, if you want to add an element at the beginning of the array, pushfirst! is the appropriate function to use.
