favorite pizza, otherwise we can only buy a pizza, It means that some people can't eat their favorite pizza, and now we need to think about what kind of pizza to buy is better, in the greedy mind, we must be for two kinds of pizza like the difference is not obvious (that is, ABS (A-B) is small), can not eat their favorite pizza, This brings the loss is the smallest, and then judge let like eat type1 eat type2, or like to eat type2 eat type1 which loss more small lost on the good.

In other words, n was multiplication of all elements of the given array.
Because of precision difficulties, Barney asked you to tell him the answer as an irreducible fraction. In all words need to find it as a fraction p/q such that, where is the greatest common divisor. Since p and Q can be extremely large, you have need to find the remainders of dividing each of the them by 109 + 7.
Please note that we want the P and Q to is 1, not the th

Map[i][j]=min (A[i],a[j]), that is, the value is the smaller of the two, and array A is a sequence that allows you to restore the array A through this array of valuesIdea: In each row if the number of different elements equals n, then this sequence except 0 think the other value is the number of series in the array A, the remaining as long as the 0 is changed to N.Another way of thinking (being taught by others) is that the maximum value in each row is actually the value of the array a[i], but

, longer lengths, i.e. larger areas After that, you can select another sequence in two, use a double loop to get the sub-columns, and then divide the limit by this sum to get a target value. After that, in the array of initial preprocessing to find the target value, return is greater than its first value, that is, with Upper_bound, to find the length minus one, so that the longest length. Finally, by multiplying the length of the lookup with the length of the current child column, the result is
