To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as follows:#include #includeintMain () {inti; floats

L2 exchange technology:The layer-2 switching technology is mature. The layer-2 switch is a data link layer device that can identify the MAC address information in the data packet and forward it according to the MAC address, the MAC addresses and corresponding ports are recorded in an internal address table. The specific workflow is as follows: 1) when the switch receives a packet from a port, it first reads

However, in this case, we cannot use a single operation to access a complete integer in A, because the elements in a are represented in binary. The only operation we can useThe operation is to take the J-bits of a [I] and the time taken is constant. Proof: if the only way to access the information in array A Is
