# Rust program to find out the first repeated element in the array

Rust | Array Example: Write a program to find out the first repeated element in the array.

Problem Solution:

In this program, we will create an array of integers then we will find the 1st repeated element in the array.

Program/Source Code:

The source code to find out the first repeated element in the array is given below. The given program is compiled and executed successfully.

```// Rust program to find out the first repeated
// element in the array

fn main()
{
let mut arr:[usize;6] = [0,1,2,3,2,3];
let mut i:usize=0;
let mut j:usize=0;
let mut item:usize=0;
let mut flag:isize=0;

while i<5
{
j=i;
while j<=5
{
if arr[i] == arr[j] {
item = arr[j];
flag = 1;
break;
}
j=j+1;
}
i=i+1;
}

if flag == 1 {
println!("{0} repeated @ {1} index", item, j)
}
else {
println!("There is no repeated element")
}
}
```

Output:

```2 repeated @ 4 index
```

Explanation:

Here, we created an array of integers with 6 elements, and then we searched the 1st repeated element in the array and printed the index of repeated elements.
