Assign the variables to values so that the following statements evaluate as described:

```
// Expression A
(x + y) > z || a == b || ((l || m) && n) // resolves to true
// Expression B
!!n && (x + y + z) && a // resolves to false
// Expression C
m[n].length + n === 1 // resolves to true
let a = 1;
let b = 1;
let l = 0;
let m = 1;
let n = 0;
let x = 1;
let y = 1;
let z = 1;
```

I don’t understand why I have a problem in the console with the .length property. I don’t even understand how (x + y + z) in expression B can be true or false. Please someone help me out.
