2526. Find Consecutive Integers from a Data Stream

For a stream of integers, implement a data structure that checks if the last kvalue.

Implement the DataStream class:

• DataStream(int value, int k) Initializes the object with an empty integer stream and the two integers value and k.
• boolean consec(int num) Adds num to the stream of integers. Returns true if the last k integers are equal to value, and false otherwise. If there are less than k integers, the condition does not hold true, so returns false.

class DataStream {
    int v,ma,c;
public:
    DataStream(int value, int k) : v(value), ma(k), c(0) {}

    bool consec(int num) {
        if(v == num) c = min(c + 1, ma);
        else c = 0;
        return c == ma;
    }
};

/**
 * Your DataStream object will be instantiated and called as such:
 * DataStream* obj = new DataStream(value, k);
 * bool param_1 = obj->consec(num);
