Consider this data sequence: "fish bird reptile reptile bird bird bird mammal fish". let's define a singleton to be a data element that is not repeated immediately before or after itself in the sequence. so, here there are four singletons (the first appearance of "fish", the first appearance of "bird", "mammal", and the second appearance of "fish"). write some code that uses a loop to read a sequence of words, terminated by the "". the code assigns to the variable n the number of singletons that were read. (for example in the above data sequence it would assign 4 to n. assume that n has already been declared. but not initialized. assume that there will be at least one word before the terminating "". assume the availability of a variable, stdin, that references a scanner object associated with standard input.

It is vital to research each of the services you plan to disable before implementing any change, especially on critical machines such as the: a. servers in the test environment. b. domain controller and other infrastructure servers. c. desktops that have previously been attacked. d. desktops used by upper-level management.

1. package newton’s method for approximating square roots (case study 3.6) in a function named newton. this function expects the input number as an argument and returns the estimate of its square root. the script should also include a main function that allows the user to compute square roots of inputs until she presses the enter/return key. 2. convert newton’s method for approximating square roots in project 1 to a recursive function named newton. (hint: the estimate of the square root should be passed as a second argument to the function.) 3. elena complains that the recursive newton function in project 2 includes an extra argument for the estimate. the function’s users should not have to provide this value, which is always the same, when they call this function. modify the definition of the function so that it uses a keyword parameter with the appropriate default value for this argument, and call the function without a second argument to demonstrate that it solves this problem. 4. restructure newton’s method (case study 3.6) by decomposing it into three cooperating functions. the newton function can use either the recursive strategy of project 1 or the iterative strategy of case study 3.6. the task of testing for the limit is assigned to a function named limitreached, whereas the task of computing a new approximation is assigned to a function named improveestimate. each function expects the relevant arguments and returns an appropriate value. 5. a list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. define a predicate issorted that expects a list as an argument and returns true if the list is sorted, or returns false otherwise. (hint: for a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return false if the first item in a pair is greater.)
