1、反转链表；
2、给你两个数组，求最小的数组平方和；力扣链接,最后写了个垃圾代码就交了;
class Solution {
public:
long long minSumSquareDiff(vector<int>& nums1, vector<int>& nums2, int k1, int k2) {
priority_queue<int> q;
for(int i=0; i< nums1.size(); i++){
q.push(abs(nums1[i]-nums2[i]));
}
int k = k1+k2;
while(k--> 0){
auto top = q.top(); q.pop();
if(top == 0)
break;
q.push(top-1);
}
long long ret = 0;
while(!q.empty()){
ret += (long long)q.top() * q.top(); q.pop();
}
return ret;
}
};
