Remove Last Item From Vector in Rust

Another way to change the data in a vector is with the .pop() method, which removes the last element from a vector:

let mut three_arr = vec![1, 4, 6];

// Remove last element:
three_arr.pop();

// three_arr is now vec![1, 4]

// Remove last element again:
three_arr.pop();

// three_arr is now vec![1]
