    }

Problem solution in C++.

class Solution {
public:
    int findKthLargest(vector<int>& nums, int k) {
        priority_queue<int> res;
        for(int i : nums)
            res.push(i);
        int ans = -1;
        while(k--){
            if(!res.empty()){
                ans = res.top();
                res.pop();
            }
        }

};

Problem solution in C.

int findKthLargest(int* arr, int size, int k){
        for(int i = 0; i < size; i++){
        for(int j = i + 1; j < size; j++){
            if(*(arr + i) > *(arr + j)){
                int t = *(arr + i);
                *(arr + i) = *(arr + j);
                *(arr + j) = t;
            }
        }
    }
    return *(arr + size - k);
}
