, the array is sorted;Then, make i=0, j=n-1, calculate arr[i]+arr[j]:If arr[i]+arr[j]>sum, then j--;If arr[i]+arr[j]If they are equal, the two number that satisfies the condition is found.Scaling Issues1. What is your solution if you change the "two numbers" in the question to "three numbers" or "arbitrary numbers"?2. If an exact pair of pairs of numbers cannot be found, can the solution be found and closest?3. Combining the two topics above, we get a title: given a number n, and a set of number

Sometimes we color-handle records for different objects in order to make the records of Excel tables easier to distinguish:such as the original data:After color processing, you want to do this:It's easy to differentiate the data by name.The specific steps are:Then proceed to the next step, filtering on the secondary column 2:Select 1 of them and turn them all into the same color:Finally, cancel the filter, and then delete the two auxiliary columns on the line:How Excel uses different

Topic:can you quickly find two numbers in an array so that the sum of these two numbers equals a given number. Solution One:exhaustive method, remove two digits from the array. Calculates whether the sum of the two is a given number. Its time complexity is N (N-1)/2, i.e. O (N2).Solution Two:Solution Three:the time complexity of the algorithm is reduced by directly conducting an orderly traversal of two numbers. sort the array first, with a time complexity of O (nlog2n)The pseudo code is as fo

of application protocols on the physical layer transmission infrastructure are all reflected in the standard advances of structured cabling systems. This is the only reason why we recommend to end users the latest final criteria for the current structured cabling system, Category 6, because it should have lower standards, such as Category 5 and Category 5, covers Application Protocols generated over a longer period of time. So, how can we ensure that

A few years ago, when I first made a bibliography guide for the search beginner, I had to calm down and think about what was the simplest and most important thing I could teach them. What do our professional searchers know, and what these students don't understand? What courses are the causes of finding and not finding differences and what they need to learn? Four words emerged in my mind, and I wrote them on a piece of paper in my office: my four search cri
