 ## Description
+You are given two arrays of integers, `fruits` and `baskets`, each of length n, where `fruits[i]` represents the **quantity** of the `ith` type of fruit, and `baskets[j]` represents the **capacity** of the `jth` basket.
+
+From left to right, place the fruits according to these rules:
+
+- Each fruit type must be placed in the **leftmost available basket** with a capacity **greater than or equal** to the quantity of that fruit type.
+- Each basket can hold **only one** type of fruit.
+- If a fruit type **cannot be placed** in any basket, it remains **unplaced**.
+
+Return the number of fruit types that remain unplaced after all possible allocations are made.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
-```
+Input: fruits = [4,2,5], baskets = [3,5,4]

-Fruits Into Baskets II
-```go
+fruits[0] = 4 is placed in baskets[1] = 5.
+fruits[1] = 2 is placed in baskets[0] = 3.
+fruits[2] = 5 cannot be placed in baskets[2] = 4.
+Since one fruit type remains unplaced, we return 1.
 ```
 
+**Example 2:**
+
+```
+Input: fruits = [3,6,1], baskets = [6,4,7]
+
+Output: 0
+
+Explanation:
+
+fruits[0] = 3 is placed in baskets[0] = 6.
+fruits[1] = 6 cannot be placed in baskets[1] = 4 (insufficient capacity) but can be placed in the next available basket, baskets[2] = 7.
+fruits[2] = 1 is placed in baskets[1] = 4.
+Since all fruits are successfully placed, we return 0.
+```
