The -- operator group of answer choices is a unary operator. subtracts one from the value of its operand. must have an lvalue, such as a variable, as its operand. can be used in either prefix or postfix mode. all of these are true.

Geneva’s manager would like to see some additional information to make sales decisions. enter a formula in cell j4 using the if function to it whether or not the item beaded earrings should go on sale. it will go on sale if its current sales rank (in cell g4) is 8th or lower. (hint: if the cell value is greater than or equal to 8, it will go on sale.)if this condition is true, the item will go on sale. (hint: the if_true value should be “yes”.)if this condition is false, the item doesn’t need to go on sale. (hint: the if_false value should be “-”.)copy the formula created in cell j4 to the range j5: j14

)a grad student comes up with the following algorithm to sort an array a[1..n] that works by first sorting the first 2/3rds of the array, then sorting the last 2/3rds of the (resulting) array, and finally sorting the first 2/3rds of the new array. 1: function g-sort(a, n) . takes as input an array of n numbers, a[1..n] 2: g-sort-recurse(a, 1, n) 3: end function 4: function g-sort-recurse(a, `, u) 5: if u ⒠` ≤ 0 then 6: return . 1 or fewer elements already sorted 7: else if u ⒠` = 1 then . 2 elements 8: if a[u] < a[`] then . swap values 9: temp ↠a[u] 10: a[u] ↠a[`] 11: a[`] ↠temp 12: end if 13: else . 3 or more elements 14: size ↠u ⒠` + 1 15: twothirds ↠d(2 ◠size)/3e 16: g-sort-recurse(a, `, ` + twothirds ⒠1) 17: g-sort-recurse(a, u ⒠twothirds + 1, u) 18: g-sort-recurse(a, `, ` + twothirds ⒠1) 19: end if 20: end function first (5 pts), prove that the algorithm correctly sorts the numbers in the array (in increasing order). after showing that it correctly sorts 1 and 2 element intervals, you may make the (incorrect) assumption that the number of elements being passed to g-sort-recurse is always a multiple of 3 to simplify the notation (and drop the floors/ceilings).

Think about a recent customer service experience - either positive or negative. write a brief summary of that experience. now think about those four characteristics we look for in customer service representatives. how did the representative in your example stack up? write down your answer and give specific examples.
