Simple way to replace nth element in a vector in clojure?

Question

E.g., I have a vector `[1, 2, 3]`, and I want to update the second element so that the vector becomes `[1, 5, 3]`. In other languages, I would just do something like `array[1] = 5`, but I'm not aware of anything that would allow me to do this easily in Clojure. Thoughts on how to accomplish this, or on whether I should be using a different data structure?

Accepted Answer

`assoc` works fine for that. It takes the index where to put the new value and return the newly created vector:

```
Clojure> (assoc [1 2 3] 1 5)
[1 5 3]
```
