[C] LeetCode how to return (int** returnColumnSizes)

returnColumnSizes.c

int* getReturnColumnSizes(int row, int col) {
    int* returnColumnSizes = (int*) malloc(sizeof(int) * 1 * row);
    
    for (int i=0; i<row; i++) {
        returnColumnSizes[i] = col;
    }

    return returnColumnSizes;
}

void main(int* returnSize, int* columnSize, int** returnColumnSizes) {
   *returnColumnSizes = getReturnColumnSizes(*returnSize, *columnSize);
}
