Read in matrix for multiple steps while changing string

Hi, I want to read in multiple temperature files at different time steps. For instance I have array:
time = [0, 10, 20];
And I need to read in:
temp0 = "temperature_0.txt"
temp1 = "temperature_10.txt"
temp2 = "temperature_20.txt"
So I can compile them all into:
temp = [temp0;temp1;temp2]
How can I handle changing the string names "temp0" and "temperature_0.txt" based on the value in time? I know I will have a for loop such as follows, but I am unsure of how to make the variable input into the name as a string
for k = 1:length(time)
...
end

time = [0, 10, 20];
files = "temperature_" + time + ".txt"
Now you could iterate over the elements of the files string array.

If the only digits in the names are in the numbers you want to extract, use digitsPattern to extract that data from the string array.
time = [0, 10, 20];
files = "temperature_" + time + ".txt"
numbersAsText = extract(files, digitsPattern)
numbers = double(numbersAsText)
isequal(time, numbers)
