    if name == 'main':

    n = int(input().strip())
binary = bin(n)[2:]
max_consecutive = max(len(ones) for ones in binary.split('0'))
print(max_consecutive)

    In C++:

    int maxConsectiveOnes(int n){ string binary = bitset<32>(n).to_string();

    int maxCount = 0;
int currentCount = 0;

for(char bit : binary){
    if(bit == '1'){
        currentCount++;
        maxCount = max(currentCount, maxCount);
    } else {
        currentCount = 0;
    }
}

return maxCount;

    }

    int main() { string n_temp; getline(cin, n_temp);

    int n = stoi(ltrim(rtrim(n_temp)));

int result = maxConsectiveOnes(n);

cout << result;

return 0;

    }

    i dont know how i got this: python

    if __name__ == '__main__':
    n = int(input().strip())
    if n == 0:
        print("0")
    else:
        a=[]
        while n>0:
            b=n % 2
            a.append(b)
            n= n//2
        a.reverse()
        cout=1
        c=[]
        for i in range(1, len(a)):
            if a[i]==a[i-1] and a[i]==1:
                cout+=1
                if i == len(a)-1:
                    c.append(cout)
            else:
                if a[i]== 1 or a[i-1]:
                    c.append(cout)
                    cout=1
        print(max(c))

    n = int(input().strip())
bin_str = bin(n).__str__()[2:]
print(len(max(re.findall(r"(1{1,})", bin_str))))
