Test Instructions: to n number, from n number of x (x>=1) number, this X number is multiplied by the total square number, to find a total number of ways, the result modulo 1000000007.idea: each number can be split into prime numbers multiplied by the form, for example:X1 2=2^1 * 3^0 * 5^0;X2 3=2^0 * 3^1 * 5^0;X3 4=2^2 * 3^0 * 5^0;X4 5=2^0 * 3^0 * 5^1;X5 6=2^1 * 3^1 * 5^0;X6 15=2^0 * 3^1 * 5^1;Use XI to indicate the number of selected or not selected,

Returns the maximum number of steps of multiplication and division. x ^ N can be obtained.
In fact, the answer is a maximum of 13, but because the branches of the tree are extremely large, while iddfs, we need to add two pruning
1 If the maximum value of the current sequence is M * 2 ^ (DEP-k)
2. If there are two numbers greater than N, the Branch is subtracted. Because there is only one useful one, we can get the answer through another shorter path.
The program looks very slow, over Ms

The probability of breathing difficulties due to smoking and bronchitis is indicated by P (D | C, B.
Lung Cancer is simplified to C, Bronchitis is simplified to B, dyspnoea is simplified to D, and C = 0 indicates the probability that lung Cancer will not ha

If sus contains multiple uplinks and multiple uplinks are from the same VC module, you must configure lacp in the external switch to ensure that uplinks are active.
