to shuffle, you have n cards, first throw away, and then put the first one in the end, and then the first card to throw away, the remaining one card and then output you throw away this card. Would have thought of using an array analogy, similar to Joseph Ring. But GG, I tried a few groups did not, and then they were hanging in that, changed a long array suddenly found a lot of people ac, I think maybe the array is more troublesome, I need to shake clever think of some other data structure, a be

Subject address: Ultraviolet A 11134 This is because the rows and columns are irrelevant and have no impact on each other. Therefore, you can separate rows or columns for calculation. This is equivalent to converting to selecting n different integers in the period [1, N], so that the I-th integer is within the Closed range [Li, Ri. This is a greedy problem. However, note that you cannot sort by left endpoint first, then by right endpoint, and then try to put it on the left, such as (), (), (). T

Subject address: Ultraviolet A 120 Question. Shift from the largest start, and each time the big one is first moved to the top and then to the bottom. The Code is as follows: #include (White Book Training Program) ultraviolet A 120 stacks of flapjacks (constructor)

Subject address: Ultraviolet A 1152 First, enumerate the sum of set a and Set B, and then enumerate the sum of set C and set D to see how many values are opposite to each other. Question. You can use binary to find the stored value. The Code is as follows: #include (White Book Training Program) fig 1152 4 values whose sum is 0 (midway encounter ..)

Subject address: Ultraviolet A 11572 This method has been used before. It defines two pointers and continuously slides from left to right to determine whether the pointer meets the requirements. In order to quickly determine whether this number exists, set in STL can be used. The Code is as follows: #include (White Book Training Program) ultraviolet (11572 unique snowflakes)
