rustHow to swap elements in a Rust slice?
Swapping elements in a Rust slice can be done using the swap
method. This method takes two indices as arguments and swaps the elements at those indices.
Example
let mut v = [1, 2, 3, 4];
v.swap(0, 3);
Output example
[4, 2, 3, 1]
Code explanation
let mut v = [1, 2, 3, 4];
: Declares a mutable slicev
with elements1
,2
,3
, and4
.v.swap(0, 3);
: Calls theswap
method onv
with arguments0
and3
, which swaps the elements at indices0
and3
