To make calculations easier for BS students (you know why), the sum contains only the numbers 1, 2 and 3. But that\u0027s not enough for Bota. She decides to count sums in non-decreasing order. For example, instead of calculating the sum 1+3+2+1, she calculates the sums 1+1+2 and 3+3.\n\nYou got the sum.
