Is it a compiler bug?

  • 0

    Here is my code,

    int removeDuplicates(int* nums, int numsSize) {
    if (numsSize <= 1) {return numsSize;}
    int compared_pointa= 0;
    int compared_pointb = 1;
    int change_point= 1;
    while(compared_pointb < numsSize) {
        if((nums[compared_pointa] == nums[compared_pointb]) &&
           (change_point - compared_pointa == 1)) {
        } else if (nums[compared_pointa] != nums[compared_pointb]) {
                nums[change_point] = nums[compared_pointb];
                compared_pointa = change_point;
    nums = (int*)realloc(nums, (change_point+1)*sizeof(int));
    return change_point;

    The submission result keeps showing that there is runtime error on my code. The last executed input is
    [1,1,2,2,3,3,4,4]. But when I tried this input, my answer and the expected answer is totally the same (both are [1,1,2,2,3,3,4,4]). I am wondering it is my fault or just a complier bug?
