- Double trouble def double_trouble(items, n): Suppose, if just for the sake of argument, that the following operation is repeated n times for the given list of items: remove the first element, and append that same element twice to the end of items. Which one of the items would be removed and copied in the last operation performed?Sure, this problem could be finger-quotes “solved” by actually performing that operation n times, but the point of this exercise is to come up with an analytical solution to compute the result much faster than actually going through that whole rigmarole. To gently nudge you towards thinking in symbolic and analytical solutions, the automated tester is designed so that anybody trying to brute force their way through this problem by performing all n operations one by one for real will run out of time and memory long before receiving the answer, as will the entire universe.To come up with this analytical solution, tabulate some small cases (you can implement the…arrow_forward1. Display Function Implement a function to display the contents of the patient_list array. Add code to call this function. Note that there are multiple places where this function needs to be called. Look for the // TODO comments to find the correct locations. Compile and test your program. Make sure that your output is formatted similarly to the sample output shown at the end of this document. The sorting part does not need to work yet. Take a screenshot of a sample output and upload the picture as part of your assignment submission. 2. Sorting the array by Age Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library(see http://www.cplusplus.com/reference/cstdlib/qsort/). As shown in the reference, this code requires two parts: A function that compares two patient elements, based on the value stored in the age…arrow_forwardPHP* Create a function that takes a list of numbers and returns the second largest number with the user input.

- POEM List[POEM_LINE] PRONUNCIATION_DICT Dict[str, PHONEMES] Do not add statements that call print, input, or open, or use an import statement. Do not use any break or continue statements.arrow_forwardC++ Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Ex:Initial scores: 10, 20, 30, 40 Scores after the loop: 30, 50, 70, 40 The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same. #include <iostream>using namespace std; int main() {const int SCORES_SIZE = 4;int bonusScores[SCORES_SIZE];int i; for (i = 0; i < SCORES_SIZE; ++i) {cin >> bonusScores[i];} /* Your solution goes here */ ////for (i = 0; i < SCORES_SIZE; i++) { This is my//// current Solution////bonusScores[i] += bonusScores[i + 1]; ////////////} for (i = 0; i < SCORES_SIZE; ++i) {cout << bonusScores[i] << " ";}cout << endl; return 0;} with the for loop i have now, the…arrow_forward1c) Average sentence length We will create a function ( avg_sentence_len ) to calculate the average sentence length across a piece of text. This function should take text as an input parameter. Within this function: 1. sentences : Use the split() string method to split the input text at every '.'. This will split the text into a list of sentences. Store this in the variable sentences . To keep things simple, we will consider every "." as a sentence separator. (This decision could lead to misleading answers. For example, "Hello Dr. Jacob." is actually a single sentence, but our function will consider this 2 separate sentences). 2. words : Use the split() method to split the input text into a list of separate words, storing this in words . Again, to limit complexity, we will assume that all words are separated by a single space (" "). (So, while "I am going.to see you later" actually has 7 words, since there is no space after the ".", so we will assume the this to contain 6 separate…arrow_forward
