Write a function that returns the sum of all the integer numbers dividable by 3 that are smaller than a given integer number. EXAMPLE sum3(20) 63

3) A function called isMagic is written below, your task is to write two of the helper functions ckRows and ckSDiagonal. ckRows checks the horizontal rows and ckSDiagonal checks the diagonal going from lower left to upper right. Each function returns true when all the individual sums of rows or the diagonal are equal to the magic number and false otherwise. An example magic square is shown, the size may not always be 3. 2 9 4 // value will be set, but may not be 5 // value will be set, but may not be 5 const int ROWS = 5; const int COLS - 5; bool isMagic(int arr[][COLS], int magic) { return ckRows (arr, magic) && ckCols(arr, magic) && 7 5 3 ckMDiagonal(arr, magic) && ckSDiagonal(arr, magic); 6 8 Your solution should be in this box: 1.

Computer Science Write a scalar function that converts kilograms to pounds and vice versa. Your function should be able to do either calculation based on a parameter value indicating which conversion is needed. The function should not accept negative values.

Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO  print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])
