JAVA PROGRAMMING Two words (spelt in uppercase) are similar if and only if all letters in the 1st word are in the 2nd word and all letters in the 2nd word are in the 1st word; including the same number of duplications. For example, ABBA and BABA are similar; however, BABA and BAAA are not similar. To check two words which are similar, we can use two integer arrays, each has 26 elements (as we have 26 letters), you can assume that 1st array element stores the number of letter ‘A’, 2nd array element stores the number of letter ‘B’, and so on. What you need to do now is to check whether the two integer arrays are equal to decide whether the two words are similar. We propose following UML for this question: The class TwoWords has two String instance variables. In this class, other than the constructors, accessor and mutator methods; we have two important methods: the countInfo method receives a String parameter (a word, for example) counts and stores the letters’ info in an integer…
Given an array of strings, return all groups of strings that are anagrams. The groups must be created in order of their appearance in the original array. Look at the sample case for clarification. Note: The final output will be in lexicographic order. Example 1: Input:N = 5words[] = {act,god,cat,dog,tac}Output:act cat tac god dogExplanation:There are 2 groups ofanagrams "god", "dog" make group 1."act", "cat", "tac" make group 2.
Write a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s. (Hint: Use two ArrayLists to store the row and column indices with the most 1s.)
In java, please read the text file as array. Then, replace the null with 0 and calculate the sum of the new students in ABC University.Example of text file: (university,year,total_students,new_students,new_staff,ABC, 2000, 3457, , ,ABC, 2001, 3675,218, ,EFG, 2000, 2389,602, ,EFG, 2001, 2785,396, 65,)
Complete the implementation of scrabble.c, such that it determines the winner of a short scrabble-like game, where two players each enter their word, and the higher scoring player wins. Notice that we’ve stored the point values of each letter of the alphabet in an integer array named POINTS. For example, A or a is worth 1 point (represented by POINTS[0]), B or b is worth 3 points (represented by POINTS[1]), etc. Notice that we’ve created a prototype for a helper function called compute_score() that takes a string as input and returns an int. Whenever we would like to assign point values to a particular word, we can call this function. Note that this prototype is required for C to know that compute_score() exists later in the program. In main(), the program prompts the two players for their words using the get_string() function. These values are stored inside variables named word1 and word2. In compute_score(), your program should compute, using the POINTS array, and return the score…
Create a function that takes a grid of # and -, where each hash (#) represents amine and each dash (-) represents a mine-free spot.Return a grid, where each dash is replaced by a digit, indicating the number ofmines immediately adjacent to the spot i.e. (horizontally, vertically, anddiagonally).Example of an input:[ ["-", "-", "-", "#", "#"],["-", "#", "-", "-", "-"],["-", "-", "#", "-", "-"],["-", "#", "#", "-", "-"],["-", "-", "-", "-", "-"] ]Example of the expected output:[ ["1", "1", "2", "#", "#"],["1", "#", "3", "3", "2"],["2", "4", "#", "2", "0"],["1", "#", "#", "2", "0"],["1", "2", "2", "1", "0"] ]Here is a tip. When checking adjacent positions to a specific position in the grid,the following table might assist you in determining adjacent indexes:NW position =current_row - 1current_col - 1N position =current_row - 1current_colNE position =current_row - 1current_col + 1W position =current_rowcurrent_col - 1Current position =current_rowcurrent_colE position…
Using java language In voltTest[10] is an encapsulated array that contains 10 voltages. Display how many are ACTIVE (5V), SATURATED (greater than 5V) and CUTOFF (less than 5V). Use the UML diagram as a reference. setValue(int,int,int) – accepts the value of voltActive, voltSaturated and voltCutoff as a parameter, which is the number of active, saturated and cutoff voltages. displayResult() – displays the number of active, saturated and cutoff voltages.
a Java method that takes an array of primitive integers as its only parameter and returns the centered average of that list as a primitive double. The centere average is defined for this question as the average of all the values in the array except for the largest and smallest values. If smallest or largest value occurs more than once, disregard only one copy of each as appropriate. the length of the array is at least 3 and every location in the array has been assigned a value
Using JavaScriptDefine a function getMonth which accepts number from 1 to 12 as an argument and return the descriptive name of the month. For example: getMonth(1) should return January while getMonth(12) returns December, finally getMonth(-1) returns null. Use array or object to define a list of names for the month and refrain from using if statement to check the argument if it's 1, 2, etc.
FOR JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.
Question 1. 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: [[""]] Explain!.
Implement this function in java : public static int [] generateRandomArr(int length, int sorted){ } The first parameter: an non-negative integer, that specifies the size (length) of the array that is created. The second parameter: an integer in the range [0, 100], inclusive, that specifies the degree to which the array's contents are sorted. If sorted=0 , the contents of the array should be in perfect reverse order. If sorted=100, the contents of the array be 100% sorted. Any value intermediate should result in an array that has approximately that % of its entries that are sorted. Hint : You can approximate this by starting with a perfectly sorted array; select at random (100%- sorted%) of the entries in the array, and override those values with a random integer greater than the value the ordered array's entries. The exception to this is when sorted=100 , in which case the array's contents must be perfectly sorted. For example, the following length and sorted parameters might result in…
