Short answer Another approach to the update algorithm is to perform use the delete function for the old value and if it is successful, call the insert function using the new value. Explain in your own words if you think this approach is significantly better, worse, or in the same category as the algorithm discussed in the slides, and why. I attached the pictures of the algorithm discussed in the slides.

- 3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends.

- Median Function – In statistics, the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, the median is the average of the two middle values. Your program should start with two arrays of integers containing the following values: Even numbered array: 17 32 45 68 99 101 67 89 22 27 Odd numbered array: 17 32 45 68 99 101 67 89 22 Using a sort function of your choice, first sort the arrays. NOTE: you may use the Standard Template Library sort function or your own sort function. Then, write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. The same function should be called twice – once for the even array and once for the odd array. Your program should also have a printArray function that can be used to print the sorted array. (It…Dynamic Array Functions XLOOKUP What is one characteristic of the XLOOKUP) function that makes it so flexible? OPTIONS: It can only take dynamic arrays as input It can be used to lookup data both vertically and horizontally It always returns a matrix of data It takes only one input parameterTask 3: Statistics using arrays: by java programming With the spread of COVID 19, the HR department in a company has decided to conduct some statistics among the employees in order to determine the number of infections according to some conditions. For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no. You need to choose one service from each category (‘A’,’B’,’C’,’D’) a. A. Display the total number of employees that were infected b. B.…

You need to partition the array into K continuous segments. For each segment, the sum of its elements needs to be calculated. The segment with the minimum sum is called the bestSegment and the sum of the elements of the bestSegment is called the bestSum. For all possible combinations of partitions of the array when divided into K segments, their bestSum needs to be calculated and the one among them with maximum value needs to be returned. Input Specification: input1: an array of N positive numbers input2: an integer N denoting the length of the array input3: an integer K Output Specification: Return an integer denoting the maximum value of all possible bestSum. Example 1: input1: (1,2,3,4} input2: 4 input3: 2 Output: 4 Explanation: You can partition the given array into 2 continuous segments in the following manner- • 123 14- the sum of individual segments is (6,4) and the bestSum is 4 • 12134- the…
