how much ps4 weigh

DescriptionFarmer John had a balance for weighing the cows. He also have a set of n (1 John has a balance to weigh the cows. It is supplied with N (1≤n≤1000) weights of known weights (all weight mass values are in 31-bit binary). Each time the cow, he put a cow on one side of the balance, and then add weights to the other side of the balance, until the balance, then the total quality of the weight is the quality of the cow (John can not put the weight

: The number of matched items is not found; Fp: False positive. The matching result is incorrect; TN: Non-matched logarithm correctly rejected; So we can get the matrix on the left and define the accuracy.(Precision)And recall rate(Recall ). Precision: Correct prediction of positive samples/All predicted positive samples; Recall: Correct prediction of positive samples/The actual value is positive; For more information about these two values, see here:Http://en.wikipedia.org/wiki/Preci

weight + 9 grams of weight + 3 grams of weight, while putting items　　 4. MetersThere is a weight of 9 kilograms and 50 grams and 200 grams respectively. How can I weigh only three times on a daily basis and claim 2 kilograms of meters?A: For the first time, you do not need to use a weight. You can place an average of 9 kilograms of rice at both ends of the balance to produce 4.5 kilograms of rice. For the second time, you can use the same method to p

optimization. Therefore, it is difficult to optimize the case as much as possible. 2) cache line alignment (Cache alignment), recommendation index: 4 stars Data spans two cache lines, which means two loads or two stores. If the data structure is aligned with the cache line, it is possible to reduce one read/write operation. The cache line alignment of the first address of the data structure, which means there may be a waste of memory (especially the continuous distribution of data structures su

Government. Therefore, the whole architectural pattern and style were modeled on the home Hall of West Road. But I did not actually live in the past. I only sent a banquet to Minister Wang. In the late Qing dynasty, when the Empress Dowager of Cixi lived in the happy life hall, they had a meal at the East warm pavilion. Emperor Guangxu lived here and met the Foreign Minister's wife with the Empress Dowager Cixi. Zhenbao PavilionThe nursing Hall is now set up as the exhibition hall of the treasu

Consistency Need to understand and weigh Strong consistency (strong consistency): always consistent Final consistency (eventual consistency): There are inconsistent time windows, but finally consistent Update consistency Problem: Write conflict (write-write conflict) Common ways to solve: Prerequisites: The order in which update operations are processed must be c

As the title says, JS | | And features help us streamline code while also bringing down code readability. This is a good example of what we need to weigh on ourselves. In the JS logical operation, 0, "", null, False, undefined, Nan will all be sentenced to false, others are true.nbsp; nbsp; | | Calculates the first operand and, if it can be converted to true, returns the value of the expression on the left, otherwise the second operand is computed.

a bitmap to record there is no situation.But there is a need to weigh the logic, is not really worth the RX SOFTIRQ to split again, divided it into the top and bottom, the scheduling cost and switching overhead in the end, the need for benchmarking to evaluate.*) to extend the execution time of net SOFTIRQ, the package has been dispatch loop. The management/control plane process is divided into separate cgroup/cpuset.5.Linux Scheduler-related modific

the cluster. A brain fissure is a communication failure that causes the cluster to be partitioned into multiple network partitions that cannot communicate with each other. The essence of cap theory: once a brain fissure occurs, the cluster is not available, and the cost is enormous, so the cluster must meet the "partitioning endurance" that the system is still available when a brain fissure occurs. This is the essence of the CAP, and the cap can be expressed as: "When a distributed system is l

　　1, Study questions(1) There are 12 balls, 1 are 9 grams, the rest are 10 grams, how to weigh three times on the balance to find the quality of the small ball of 9 grams?A: For the first time: divide 12 balls into two halves, half 6, on the balance, take the side of small quality;The second time: divide 6 balls into two halves, half three, also take the small side of quality;The third time: take three balls in any one or two to

the zoo, then every animal in the zoo is a class, tigers, swans, crocodiles, bears. They all have the same attributes, such as height, weight, birth time and variety, and a variety of actions, such as crocodiles swimming, swans flying, tigers running, and bears eating.But the tiger bears are nothing specific, but a class of animals. Although they all have height and weight, you have no way of determining how much this value is. If this time gives you a specific tiger, and you are not dead, then

Piggy-bank Typical full knapsack problem, see if it happens to be full of savings, if not full DP[F] or INF, the transfer equation is: Dp[i] = min (Dp[i], Dp[i-w[j]] + p[j]); Problem Description before ACM can do anything, a budget must is prepared and the necessary financial. The main income for this action comes from irreversibly Bound (IBM). The idea behind are simple. Whenever some ACM member has any small, he takes the coins and throws to them into a.

coupling degree. Therefore, "high cohesion" and "low coupling" is contradictory, must weigh the pros and cons, comprehensively to deal with. In the UML and pattern application of Li Yang and other people's translation, cohesion and coupling are translated into yin and yang in software engineering, which is the best explanation for Chinese cohesion and coupling. To sum up, the "high cohesion" to the software project brings advantages: Strong readabil

objects and object containers consistently, regardless of whether a single object or a combined object container is handled. Decoupling the "client code from the complex object containment structure" is the core idea of the composite pattern, and after decoupling, the client code will be dependent on the pure object interface-rather than the complex internal implementation structure of the object container-and thus more "responsive to change". In composite mode, it is a matter of "transparency"

incremental, deleted, and modified trigger on the table b-tb06 to maintain the Busi-balance column values on the B-TB01 table. Similar situations occur frequently in decision support systems. The benefit of the counter specification is to reduce the need for connection operations, to reduce the number of codes and indexes, and to reduce the number of tables, and the resulting problem is the likelihood of data integrity issues. Speed up the query, but reduce the speed of modification. Therefor

There are many kinds of female functions, the most commonly used are common type and exponential parent function. The difference between the two is: the normal type of the main function is to find a combination of the number of schemes, and the exponential female function is to find multiple permutations. The following is only an explanation of the common type parent function. definition : If the function g (x) is =a0+a1*x+a2*x^2+......+an*x^n, then the function g (x) is the parent function of
