+
+# --description--
+
+In this lab you will use a dynamic programming approach to compute and return the `n`-th number from the Fibonacci sequence, in which each number is the sum of the two preceding numbers.
+
+**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab. 
+
+**User Stories:**
+
+1. You should define an array named `sequence` in the global scope. It should contain the number `0` and `1`.
+1. You should create a function named `fibonacci`.
+1. The `fibonacci` function should take a single parameter, which is a positive integer.
+1. If the input is not a positive integer, the function should return `"Invalid input"`.
+1. A call to `fibonacci(n)` should use a dynamic programming approach to compute and return the `n`-th number from the Fibonacci sequence.
+1. Each computed number at the position `n` in the Fibonacci sequence should be stored at the index `n - 1` of the `sequence` array.
+1. If the input number requests an already computed number, no new computations should happen and the number should be retrieved from the `sequence` array.
+
+# --hints--
+
+You should have a `sequence` array.
+
+```js
+assert.isArray(sequence);
+```
+
+The `sequence` array should contain `0` and `1` at definition.
+
+```js
+assert.match(__helpers.removeJSComments(code), /(let|const)\s+sequence\s*=\s*\[\s*0\s*,\s*1\s*\]\s*;?/)
+```
+
+You should create a `fibonacci` function.
+
+```js
+assert.isFunction(fibonacci);
+```
+
+`fibonacci(3.5)` should return `"Invalid input"`.
+
+```js
+assert.strictEqual(fibonacci(3.5), "Invalid input")
+```
+
+`fibonacci(0)` should return `"Invalid input"`.
+
+```js
+assert.strictEqual(fibonacci(0), "Invalid input")
+```
+
+`fibonacci(-1)` should return `"Invalid input"`.
+
+```js
+assert.strictEqual(fibonacci(-1), "Invalid input")
+```
+
+`fibonacci("three")` should return `"Invalid input"`.
+
+```js
+assert.strictEqual(fibonacci("three"), "Invalid input")
+```
+
+`fibonacci(1)` should return `0`.
+
+```js
+assert.strictEqual(fibonacci(1), 0)
+
+```
+
+`fibonacci(32)` should return `1346269`.
+
+```js
+assert.strictEqual(fibonacci(32), 1346269)
+
+```
+
+`fibonacci(5)` should return `3`.
+
+```js
+assert.strictEqual(fibonacci(5), 3);
+
+```
+
+`sequence` should contain numbers up to the highest call so far.
+
+```js
+sequence.length = 2
+fibonacci(2)
+assert.lengthOf(sequence, 2)
+fibonacci(5)
+assert.lengthOf(sequence, 5)
+fibonacci(3)
+assert.lengthOf(sequence, 5)
+fibonacci(10)
+assert.lengthOf(sequence, 10)
+assert.deepEqual(sequence, [0, 1, 1, 2, 3, 5, 8, 13, 21, 34])
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+const sequence = [0, 1];
+
+const fibonacci = (n) => {
+    if (typeof n !== "number" || n < 1 || n % 1 !== 0) {
+        console.log("Invalid input")
+        return "Invalid input"
+    }
+    if (n <= sequence.length) {
+        return sequence[n - 1];
+    }
+    for (let i = sequence.length; i < n; i++) {
+        sequence.push(sequence[i - 1] + sequence[i - 2]);
+    }
+    return sequence[n - 1]
+}
+
+```
