His eyes watched her mother pick with eyes always affectionately close. Mother oval face with a white skin. Thin lips red under high nose looks delicate making increasingly seen as beautiful. When mother laugh look florid, just blooming roses morning. Mother hands plump, fair had raised, mentoring children from an early age they just womb. The voice of a passionate mother, while smoothly as ru language, such as birds chirped at robins morning. Her mother sewing and embroidery is very beautiful, especially the long dress, casual or dressed mother of neat, as a high school teacher mother wore a long coat and sew by her mother looks graceful, elegant.

At home, she was in charge of housework. Mother handed to me the light work such as sweeping, folding clothes ... And three, the mother extra laundry, cleaning the house clean, occasionally she bought flowers for distillation at the beautiful lounge.

e chỉ biết mỗi đề bài thôi chứ bài này khó lắm

Đề bài:

Ann và Bob có một số lượng lớn đồ ngọt mà họ đồng ý chia sẻ theo các quy tắc sau. Ann sẽ lấy một viên ngọt, sau đó Bob sẽ lấy hai viên kẹo và sau đó thay phiên nhau, mỗi người lấy một viên ngọt hơn những gì người kia vừa lấy. Khi số kẹo còn lại ít hơn số kẹo sẽ lấy ở lượt đó thì người cuối cùng lấy hết số kẹo còn lại. Trước sự ngạc nhiên của họ, khi họ ăn xong, họ đều có số kẹo như nhau

Họ quyết định thực hiện chia lại lần nữa, nhưng lần này, trước tiên, họ chia kẹo thành hai đống bằng nhau và sau đó lặp lại quy trình trên với mỗi đống. Ann đi đầu tiên cả hai lần. Họ vẫn kết thúc với cùng một số lượng kẹo mỗi loại.

Số lượng đồ ngọt tối đa ít hơn 1000 mà họ có thể bắt đầu bằng là bao nhiêu?
