Write a statement that assigns the elements shown in Figure 8-87 to a two-dimensional array with implicit sizing named intPinNumbers.

Given an array of integers named ages, which of the following will query this array to get all values less than 20 and store the result in teens? Question 8 options:   a)  int teens = from item in ages            where item < 20            select item;   b)  var teens = from ages            where item < 20            select item;   c)  var teens = from item in ages            where item < 20            select item;   d)  var ages = from item in teens           where item < 20           select item;

Write a ‘for’ loop to calculate ‘sum2’ (sum of all elements of column ‘2’) and ‘sum3’ (sum of all elements of column ‘3’).then write an ‘if’ statement to check whether ‘sum2’ is greater than ‘sum3’. If True, use ‘fprintf’ function to print ‘sum2 is higher’ in your command window.Use array operations to find element-by-element multiplication of column ‘2’ and column ‘3’.2 FOR MATLAB! Thanks :) the document can be named something like sample.xlsx

Need help fixing this Merge Sort. Im using Visual Basic and does not compilate

Declare a function named contains_char. Its purpose is when given two strings, the first of any length, the second a single character, it will return True if the single character of the second string is found at any index of the first string, and return False otherwise.

TicTacToeCreate the board display the board Set token to ‘x’Loop //at most 9 times, but end loop when someone wins{ Ask player where to place token display the board Checks if won Change token (if it was ‘x’ change to ‘o’ and vice versa)}Either congratulate someone on winning or say it was a draw. Create a 17x17 array of characters and put ‘ ‘ in each element.2. Write a loop to make the first horizontal line, and another to do the second horizontal line3. Write a loop to make the first vertical line, and another to create the second vertical line4. Put in the numbers (this is so the player can choose where to put the token). You will need 9 separate assignment statements.

A(n) ___ is used in an array to across each element?   a. Index   b. Subscript   C. Both a and b   d. None of the above

Create a visitors application that prompts the user for the number of visitors each day for the past 5 days and then displays the average number of visitors per day. (use & to accept new value) Use PL/SQL Array  (NUMBER type basic composite array type )  and array has to have 5 members only.  The application output should look like same as following:   Test:  If you receive below numbers from user then your average should be 234. Display avarage on screen.   1:    150   2:    220   3:    180    4:    300   5:    320   The average number of visitors is:     234   Hint : Once you create  Array  DECLARE      TYPE    my_array_type  IS TABLE OF   number INDEX BY PLS_INTEGER;      v_n_array    my_array_type;   Then in the BEGIN and END block   accept new value for each array members.  DO NOT Use LOOP to accept new & as it is not design to get new value via loop..  Instead use separate 5 different &substitution value to get each values from user input   BEGIN…
