) According to our assumptionsBx2 + (a-a/B * B) y2 = gcd (B, a-a/B * B) ThereforeAx1 + by1 = bx2 + (a-a/B * B) y2 = ay2 + (x2-a/by2) B ThereforeX1 = Y2, Y1 = x2-A/by2 While,For anyA, BIfB! = 0Perform the following iteration:A = B, B = A % B EventuallyB = 0 Then we can carry out iterative solutions based on the above theorem.

Using the knowledge of permutation and combination, we can calculate that n bit can represent 2 ^ n cases, for example, 3 bit can represent 8 conditions:000 001 010 011 100 101 110 111Now we stipulate that in the n bits, if this bit is 1, then from right to left, how many BITs is this bit: Suppose it is t, then t is selected: for example: in 110, 3 and 2 are sele

Special case: there are n steps and only one or two steps can be taken at a time. How many steps can be taken? Int getnum (int n){If (n> 2){Return getnum (N-1) + getnum (N-2 );}Else if (n = 2)Return 2;Else if (n = 1)Return

the data sent by the client, or if you only cache data of the same size, you can reduce waste if you use a list of groups that fit the data size.Unfortunately, it is not possible to perform any tuning at this time, only to look forward to future versions. However, we can adjust the difference in the size of the slab class. Next, the growth factor option is described.Tuning with growth factormemcached specifies the growth factor factor at startup (with the-f option) to control the difference bet
