Suppose we have a document of D distinct words and we want to return the N most frequently occuring words in the document. Assume N is much less than D. Describe the fastest algorithm (clearly list each step of the algorithm) to solve this problem, starting with a hash table in which to store the frequencies. You may use additional structures, as long as they are one of the structures covered in class. Make sure to specify what is the key and what is the value for all structures used. Against each step of your algorithm, write down the big 0 running time with an explanation of how you got it, and specify whether this running time is expected time or worst case time. You can use known-from-class structures you use, **but you still have to write what the actual running time is**

Make this program in PERL programming, we can use (file, references to array, hash, associative arrays, modules, exporting) Introduction Let us consider the case of the customer database of a supermarket. The problem of searching is examined. It is considered that the database is ready and there is not update operations. The purpose is to search the records using as key the phone number, or the email. Problem Search the database and find the customers. File (customers.txt) Sonto,Peter (508)-555-8930 sontop@aol.com Wood,Ann (510)-666-3450 wooda@zen.org Jones,Jo (230)-552-3420 jonesj@cany.org Jeter,Lin (220)-333-3220 leterl@rain.com Search: Giving the email you can get all the information . You can exit from searching by typing : q (quit). Hint: You have to create the file by a notepad
The goal is to rewrite the function, below, such that passes in a different list of parameters, particularly eliminating the need to pass low and high for each recursive call to binary_search. defbinary_search(nums,low,high,item): mid=(low+high)//2iflow>high:returnFalse #The item doesn't exist in the list!elifnums[mid]==item:returnTrue# The item exists in the list!elifitem<nums[mid]:returnbinary_search(nums,low,mid-1,item)else:returnbinary_search(nums,mid+1,high,item) The new function should be prototyped below. The number of changes between the given version, and the one requested is not significant. defbinary_search(nums,item):pass# Remove this and fill in with your code Tip: If you consider that high and low are used to create a smaller version of our problem to be processed recursively, the version requested will do the same thing, just through a different, more Pythonic technique.
by using c++. How can I solve this? Kindly, no class, linked list, and pointers shall be used in this program. Kindly use only SELECTION, ITERATION, INPUT, AND OUTPUT, FUNCTION, ARRAY, AND STRING ONLY.
Need help with this python question. You can't use break, str.endswith, list.index, keywords like: await, as, assert, class, except, lambda, and built in functions like: any, all, breakpoint, callable. Create a recursive function def ab_equal(n, k, current): Print out all of the strings of a's and b's of length n so that the number of a's and b's are equal. For n = 2, there's ab and ba. For n = 3 there are no strings since they'd have to have 2 a's and 1 b, or 2 b's a 1 a so not equal. For n = 4, there will be 6 of these strings, and for n = 5, zero again. Hint: use k to track the difference between a's and b's. So for instance if your current is aaabb then k should be equal to either 1 or -1 (your choice depending). When you call the function, you should call it from your main or testing function with the length in the n parameter, 0 should be put into the k parameter, and then an empty string will be passed in for current.
