+
+- Difficulty:  `#easy`
+- Category: `#ProblemSolvingBasic` `#greedy` `#sorting`
+
+Mark and Jane are very happy after having their first child.
+Their son loves toys, so Mark wants to buy some.
+There are a number of different toys lying in front of him,
+tagged with their prices.
+Mark has only a certain amount to spend, and he wants to maximize
+the number of toys he buys with this money.
+Given a list of toy prices and an amount to spend,
+determine the maximum number of gifts he can buy.
+
+**Note** Each toy can be purchased only once.
+
+## Example
+
+The budget is `7` units of currency. He can buy items that cost `[1, 2, 3]`
+for `6`, or `[3, 4]`, for  units.
+The maximum is `3` items.
+
+## Function Description
+
+Complete the function maximumToys in the editor below.
+
+maximumToys has the following parameter(s):
+
+- `int prices[n]`: the toy prices
+- `int k`: Mark's budget
+
+## Returns
+
+- `int`: the maximum number of toys
+
+## Input Format
+
+The first line contains two integers, `n` and `k`, the number of priced toys
+and the amount Mark has to spend.
+The next line contains `n` space-separated integers `prices[i]`
+
+## Constraints
+
+- $ 1 \leq n \leq 10^5 $
+- $ 1 \leq k \leq 10^9 $
+- $ 1 \leq prices[i] \leq 10^9 $
+
+A toy can't be bought multiple times.
+
+## Sample Input
+
+```text
+7 50
+1 12 5 111 200 1000 10
+```
+
+## Sample Output
