### 方法一
### 方法一:贪心 + 差分数组 + 优先队列(大根堆)

<!-- tabs:start -->

#### Python3

```python

class Solution:
def maxRemoval(self, nums: List[int], queries: List[List[int]]) -> int:
queries.sort()
pq = []
d = [0] * (len(nums) + 1)
s = j = 0
for i, x in enumerate(nums):
s += d[i]
while j < len(queries) and queries[j][0] <= i:
heappush(pq, -queries[j][1])
j += 1
while s < x and pq and -pq[0] >= i:
s += 1
d[-heappop(pq) + 1] -= 1
if s < x:
return -1
return len(pq)
```

#### Java

```java

class Solution {
public int maxRemoval(int[] nums, int[][] queries) {
Arrays.sort(queries, (a, b) -> Integer.compare(a[0], b[0]));
PriorityQueue<Integer> pq = new PriorityQueue<>((a, b) -> b - a);
int n = nums.length;
int[] d = new int[n + 1];
int s = 0, j = 0;
for (int i = 0; i < n; i++) {
s += d[i];
while (j < queries.length && queries[j][0] <= i) {
pq.offer(queries[j][1]);
j++;
}
while (s < nums[i] && !pq.isEmpty() && pq.peek() >= i) {
s++;
d[pq.poll() + 1]--;
}
if (s < nums[i]) {
return -1;
}
}
return pq.size();
}
}
```

#### C++

```cpp

class Solution {
public:
int maxRemoval(vector<int>& nums, vector<vector<int>>& queries) {
sort(queries.begin(), queries.end());
priority_queue<int> pq;
int n = nums.size();

pq.pop();
--d[end + 1];
}
if (s < nums[i]) {
return -1;
}
}
return pq.size();
}
};
```

#### Go

func (h *hp) Pop() any {
a := h.IntSlice

h.IntSlice = a[:len(a)-1]
return v
}
```

#### TypeScript

```ts
function maxRemoval(nums: number[], queries: number[][]): number {
queries.sort((a, b) => a[0] - b[0]);
const pq = new MaxPriorityQueue<number>();
