There are two n-element arrays A and B the task is to permute them such that A[i]+b[i]>=k Can someone walk me through the code. I dont understand the iList and jList and why we have if j and i not in List we do List.append. Also at the end why we do if len(iList)+len(jList)==len(A)+len(B)? def twoArrays (k, A, B): A.sort() B.sort() iList = [] jList = [] for i in range (len (A)): for j in range (len (B)): if(A[i]+B[j]>=k): if j not in jList and i not in iList: iList.append(i) jList.append(j) print (iList) print (jList)

Write down code that asks user to enter elements of list to get sorted. The system then sorts lists in descending order. Make your program modular.
Using STL write main program to Create a list of data type double. Initialize it from an array of your choice. Cout its cubic sum as below n > list(i)3 n = size of list i=0
This code crashes when it is run. Why? mystr = "12345" mystr[2] = '9' lists cannot be changed by assignment to individual element b. strings are immutable the '9' should be just 9 d. a. с. the 2 is too large for the range e. the 9 would make the digits out of order
MASM IRVINE 32 library PROGRAM. How do you take a SORTED array of elements and count the amount of each integer in that list and then display it. So if i had a list of [1,2,4,1,4,2,1,4,1,2,4,5,2]. I need to make a program that can iterate through that and find the amount of 1s, 2s, 3s, 4s etc and display it. MUST BE IN MASM IRVINE 32 LIBRARY.
A student writes a program that for any two lists L1 and L2, computes a list L3 that contains only the elements that are common between the two lists *without duplicates*. Which following statement makes the following portion of code that computes L3 correct: L3 = [] # line 1 for elem in L1: # line 2 if elem in L2: # line 3 L3.append(elem) # line 4
Write a program REMOVE_DUPLICATES that will remove duplicateelements in a list L that occur consecutively. The program should return the list withits elements in the same order of their appearance in the original list, but with theconsecutive duplicate elements removed.
Language: Python 3 Autocomplete Ready O 4. Pair Of Elements having Smallest Absolute Difference 1 v import ast lst = input() 2 3 lst = ast.literal_eval (lst) 4 Given a list of unsorted integers. Find the pair of elements that have the smallest absolute difference between them. If there are multiple pairs, find them all. 5 6 print(smallest_absdiff_pairs(lst)) Implement a function smallest_absdiff_pairs that take a list of numbers and returns a list of pair of elements that have the smallest absolute difference between them. >>> smallest_absdiff_pairs([5, 4, 3, 2]) [(2, 3), (3, 4), (4, 5)] >>> smallest_absdiff_pairs([-20, -3916237, -357920, -3620601, 7374819, -7330761, 30, 6246457, -6461594, 266854, -520, -470]) [(-520, -470), (-20, 30)] >>> smallest_absdiff_pairs([-20, -3916237, -357920, -3620601, 7374819, -7330761, 30, 6246457, -6461594, 266854]) [(-20, 30)]
When a list is implemented using an array, which of the following is FALSE? Select one: A.If the size of the array is insufficient, there is a need to copy the whole list to a new array B.The new node inserted might cause shifting of the existing elements C.The memory allocation can be very inefficient D.The insertion of a new element is proportional to the size of the list
Complete the reverse_list() function that returns a new string list containing all contents in the parameter but in reverse order. Ex: If the input list is: ['a', 'b', 'c'] then the returned list will be: ['c', 'b', 'a'] Note: Use a for loop. DO NOT use reverse() or reversed(). This is my code so far: def reverse_list(letters): for x in (letters): letters.sort(reverse=True) return lettersif __name__ == '__main__': ch = ['a', 'b', 'c'] print(reverse_list(ch)) # Should print ['c', 'b', 'a'] When submitting I get 4/10 and it says: Test input list ['a', 'b', 'c'] returns ['c', 'b', 'a'] Your output reverse_list() function reversed array incorrectly: ['c', 'b', 'a'] reverse_list() function should have returned: ['a', 'b', 'c'] Test input list ['a', 'b', 'c', 'd'], first element of returned list is ['d'] Your output First character of returned array should be a instead of d Test empty input array TypeError: object of type 'NoneType' has no len()
Python Help Write a function equals(a,b) that returns true when the two lists a, and b have the same elements in the same order, and false otherwise.Write main() to call the function equals(a,b)
There are many differences between array and linked list, one of these differences: a. In a linked list insertion and deletion takes more time b. Array supports random access while linked List supports sequential access c. in linked list, elements are stored in contiguous memory location while in array are stored anywhere in the memory d. None of the above
Write a program that implements a sorted list using dynamic allocated arrays. DataFile.txt contains the information of poker cards. C: clubs(lowest),D: diamonds, H: hearts, S:spades(highest) 2 (lowest), 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A No Joker cards Any C cards are lower than any D cards. DataFile Content(You can write the file specification into your program.): H4,C8,HJ,C9,D10,D5,DK,D2,S7,DJ,H3,H6,S10,HK,DQ,C2,CJ,C4,CQ,D8,C3,SA,S2,HQ,S8,C6,D9,S3,SQ ,C5,S4,H5,SJ,D3,H8,CK,S6,D7,S9,H2,CA,C7,H7,DA,D4,H9,D6,HA,H10,S5,C10 H4, D5, HK, D2 H4, HK, SK C9,C10 For examples, DJ means J of Diamonds;H7 means 7 of hearts. Your job Create a list by dynamic allocated array and set the size to 20 Read the first 20 cards in the first line of the file, the put them one by one into the list by implementing and using putItem(). The list must be kept sorted in ascending order. Then print out all the cards in the list in one line separating by commas. Then delete the cards indicated in the second…
