Rated power refers to the power of the normal operation of the appliance. Its value is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the electrical appliance may be damaged, and if the actual power is less than the

A more efficient approach is to use integer division and modulo to compute quotient and remainder:
R k ≡ rk−2 mod rk−1

As the heart of the computer hardware system, although the power supply does not determine the performance, it determines the stability and durability of performance. Our knowledge of the power supply is wrapped in a metal shell. This also greatly reduced our understanding of the power supply, we need only through the power supply nameplate, Power module composition and so on can see the origin of power and quality. However, although this is not enough, because of artificial misleading and netwo
The user shall select the required UPS Output Power KVA value based on the statistical value of the device load). To ensure the UPS system efficiency and prolong the UPS Service life as much as possible, the recommended parameters are: the user load only accounts for 60% of the UPS output power ~ 70% is recommended.

, 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

A. diverse substring (prefix and)
Question: Give a string, find a substring that meets the requirements of each letter in the substring to appear no more than the length of the substring/2, the length of the string n
Question: the starting and ending points of the N-party enumerative substrings. Create a prefix for each letter and you will be able to know the number of each letter in any string.
