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)

You are given an array-like data structure Listy which lacks a size method. It does, however, have an elementAt ( i) method that returns the element at index i in 0( 1) time. If i is beyond the bounds of the data structure, it returns -1. (For this reason, the data structure only supports positive integers.) Given a Listy which contains sorted, positive integers, find the index at which an element x occurs. If x occurs multiple times, you may return any index. Write code with explanation

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…
