Question

if a duplicated letter is found in the string given by the person it should return true and if there is no dupllicated letters must return false

every str i input it just returns true so im not sure whats wrong in the code

a = 0
b = 0
def duplicate_letters(a: int, b: int):
for a in range(len(word_input)):
if (word_input[a]
word_input [b]):
==
return True
for b in range(len(word_input)):
if (word_input[a] != word_input [b]):
return False

A grid needs a system for numbering the tiles in order to allow random-access lookup.For instance, the rows and columns of a square grid provide a natural numbering for the tiles. Create plans for hexagonal and triangular grids. Create a rule for identifying the neighbourhood (i.e., nearby tiles) of a certain tile in the grid using the numbering scheme. For instance, the neighbourhood of tile I j in a four-connected square grid with indices of I for rows and j for columns may be described as neighbourhood(i, j) = I 1, j, I j 1.
java Given a String [] arr, print a pair of items together in one line until all the pairs are printed. A pair is a element and the element next to it. Print each item with a comma in between them. Scanner input = new Scanner(System.in); String[] arr = new String[8]; for (int i=0;i<8;i++){ arr[i] = input.nextLine(); } Input: [apple, banana, kiwi, grape, milk, soda, juice, coffee] Output: apple, banana banana, kiwi kiwi, grape grape, milk milk, soda soda, juice juice, coffee
Here__Given an m x n 2D binary grid grid which represents a map of '1's (land) and '0's (water), return the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. You may assume all four edges of the grid are all surrounded by water. Example 1: Input: grid = [ ["1","1","1","1","0"], ["1","1","0","1","0"], ["1","1","0","0","0"], ["0","0","0","0","0"] ] Output: 1 Example 2: Input: grid = [ ["1","1","0","0","0"], ["1","1","0","0","0"], ["0","0","1","0","0"], ["0","0","0","1","1"] ] Output: 3.

Given a input.txt: 42 4 0 02 0 0 00 0 0 00 0 8 0 where 4 is the size of the matrix that has the same row and column. 1 is up, 2 is right, 3 is down and 4 is left. For example, if the command is 1, all the elements besides zero in the matrix will move up to the top. also, when moving numbers to one side, two identical numbers can be merged to the double value of the numbers. so from: 2 4 0 02 0 0 00 0 0 00 0 8 0 now will be 4 4 8 00 0 0 00 0 0 00 0 0 0 and now if the matrix move to the right, it will be from: 4 4 8 00 0 0 00 0 0 00 0 0 0 to 0 0 8 80 0 0 00 0 0 00 0 0 0. Please help using C++, stack and linked list so that every time when I do up, down, left, right it will output the same as above. Please write explanation for every line. Thank you so much!!!

A bit (meaning binary digit) is 0 or 1. An ordered array of eight bits (such as01101001) is a byte. How many different bytes are there? If you select a byte at random, what is the probability that you select 11000010? What is the probability that you select a byte containing three 1’s and five 0’s?
java Given an int [] nums, print true if the array has a 5 that is also next to another 5. Both conditions need to be met otherwise print false Scanner input = new Scanner(System.in); int[] nums = {input.nextInt(),input.nextInt(),input.nextInt(),input.nextInt(),input.nextInt()}; Input: [1, 5, 5, 1, 1] Output: true
Given an array of strings strs, group the anagrams together. You can return the answer in any order. An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. Example 1: Input: strs = ["eat","tea","tan","ate","nat","bat"] Output: [["bat"],["nat","tan"],["ate","eat","tea"]] Example 2: Input: strs = [""] Output: [[""]].
