True/False?: If an array is dimensioned as follows, it must contain 20 elements:
DIM Table(0 TO 20) Explain

Answer: ------- False Explanation: --------------- DIM Table(0 TO 20) This statements creates an array with indexes from 0 to 20. so, the array has 21 element, not 20.

Suppose you have an array of n elements containing three distinct keys, true, false, and maybe. Give an O(n) algorithm to rearrange the list so that all false elements precede the maybe elements, which in turn precede all true elements. You may use only constant extra space.
25. Given the array declaration double xyz [20]: which of the following statements are true? a. The array may hold up to 20 elements which may be accessed by the subscripts 0 through 20 b. The array may hold up to 21 elements which may be accessed by the subscripts 0 through 20 c. The array may hold up to 21 elements which may be accessed by the subscripts 0 through 19 d. The array may hold up to 20...
Say true or false and explain it. A heap is represented using an array. The array {0 1 3 4 8 2} is a heap.The array {65 43 6 33 40 45} is not a heap.
Question 1 When you declare a variable of type Single, it contains 0 by default. True False Question 2 The following line declares an array that can contain whole numbers, with 10 elements. Dim Variables(9) As Integer True False Question 3 Once a variable is declared we can not change the variable's data type. True False Question 4 If A is False and B is True, then A Or B is True because A is False. True False Question 5...
State whether each of the following is true or false. If false, explain why: a.Referring to an array element outside the array bounds is a syntax error. b.When initializing an array at its declaration, it is a syntax error to provide less initializers than the number of array elements. c.A character array can be initialized using a string literal. d.An individual array element that is passed to a function and modified in that function will contain the modified value when...
True/False) If A is regular, and A = A, then B must be not regular. True/False) Given three languages A, B, C where . If both A and B are regular, then C must be regular. (Hints: Æ} True/False) Suppose we have proved that A = {0n1n: n ≥ 0 } is not regular. Then we can prove the following language is not regular as follows. B = {0m1n : ; m, n ≥ 0 }
