You did not initialise the pre array with zero. Also before test case, you should update all the values of pre array as 0. So it is recommended to define the pre[1000005] = {0}; inside the test cases loop or use a vector (initialised with 0) and clear it after each test case.

If further doubts, feel free to raise the query again.

I said to define the array inside the test cases loop but you only initialised it by 0.
I have updated the code and please check now.
