# tensorflow:: ops:: SetDiff1D

``` #include <array_ops.h> ```

Computes the difference between two lists of numbers or strings.

## Summary

Given a list ``` x ``` and a list ``` y ``` , this operation returns a list ``` out ``` that represents all values that are in ``` x ``` but not in ``` y ``` . The returned list ``` out ``` is sorted in the same order that the numbers appear in ``` x ``` (duplicates are preserved). This operation also returns a list ``` idx ``` that represents the position of each ``` out ``` element in ``` x ``` . In other words:

``` out[i] = x[idx[i]] for i in [0, 1, ..., len(out) - 1] ```

For example, given this input:

```x = [1, 2, 3, 4, 5, 6]
y = [1, 3, 5]
```

This operation would return:

```out ==> [2, 4, 6]
idx ==> [1, 3, 5]
```

Args:

• scope: A Scope object
• x: 1-D. Values to keep.
• y: 1-D. Values to remove.

Returns:

• ``` Output ``` out: 1-D. Values present in ``` x ``` but not in ``` y ``` .
• ``` Output ``` idx: 1-D. Positions of ``` x ``` values preserved in ``` out ``` .
