Question: 15.Consider the following function typoglycemia , which takes as input a valid string s , containing at least one character. It is intended to return

15.Consider the following functiontypoglycemia, which takes as input a valid strings, containing at least one character. It is intended to return a string formed by taking the first and last letter of each of the words in the input string, as well as the space in between words. Return 'Error' if the input string is only one word.

DEFINE typoglycemia(s)

size = 0

abbr=""

FOR i = 0 TO length(s) BY 1 DO

IF (s[i]==' ') AND (i < length(s) - 1) THEN

size = size + 1

abbr = abbr + s[i - 1]

abbr = abbr + s[i]

abbr = abbr + s[i + 1]

ELSEIF (i==0) THEN

abbr = abbr + s[i]

ELSEIF (i==(length(s)-1)) THEN

abbr = abbr + s[i]

ENDIF

ENDFOR

IF ( /* missing code 1 */) THEN

/* missing code 2 */

ELSE

/* missing code 3 */

ENDIF

ENDDEF

Which of the following can be used to replace /* missing code 1 */, /* missing code 2 */, and /* missing code 3 */ so thattypoglycemiaworks as intended. For example, the function call typoglycemia("Can you read this ?") would return the following line:

-/* missing code 1 */ length(abbr) != 0

/* missing code 2 */ RETURN abbr

/* missing code 3 */ RETURN "Error"

-/* missing code 1 */ length(s) == 0

/* missing code 2 */ RETURN "Error"

/* missing code 3 */ RETURN abbr

-/* missing code 1 */ size == 0

/* missing code 2 */ RETURN "Error"

/* missing code 3 */ RETURN abbr+typoglycemia(s.substring(1:length(s)))

-/* missing code 1 */ size == 1

/* missing code 2 */ RETURN abbr

/* missing code 3 */ RETURN "Error"

-/* missing code 1 */ size == 0

/* missing code 2 */ RETURN "Error"

/* missing code 3 */ RETURN abbr

DEFINE reverse(s)

IF ( /* missing code l */) THEN

/* missing code 2 */

ENDIF

ENDDEF

Write code to fill in /* missing code l */, /* missing code 2 */, and /* missing code 3 */ to complete the mirror function such that it prints the mirror image of a valid string s, where s is a non-empty string. For example the function call reverse ("Computers") would print

'sretupmoC'

-/* missing code 1 */ length(s) == 0

/* missing code 2 */ RETURN ""

/* missing code 3 */ RETURN s[length(s) - l] +

reverse(s.substring(0 : length(s) - 1))

-/* missing code 1 */ length(s) == 1

/* missing code 2 */ RETURN s[0]""

/* missing code 3 */ reverse(s.substring(0 : length(s) - 1))

-/* missing code 1 */ length(s) == 0

/* missing code 2 */ RETURN s[0]""

/* missing code 3 */ reverse(s.substring(0 : length(s)-1))

-/* missing code 1 */ length(s) == 0

/* missing code 2 */ RETURN s[0] ""

/* missing code 3 */ RETURN s[length(s) - l] +

reverse(s.substring(0 : length(s) - 1))

-/* missing code 1 */ length(s) == 1

/* missing code 2 */ RETURN ""

/* missing code 3 */ reverse(s.substring(1 : length(s) - 1))

20.Given the function definition for computing the displacement of an object:

DEFINE calculate (a, b, c)

solution= a * c + 0.5 * b * c * c

RETURN solution

ENDDEF

And the following code statements:

x = 3

y = 12

z = 9

solution = calculate(x, y, z)

Which of the following statements is true after the call tocalculate( x, y, z)has completed execution?

-The order of inputs to the function call is unimportant; the function definition declares how the inputs are used. e.g.,

calculate(x, y, z) == calculate(y, x, z)

-a, b, and c are undefined.

-a = 3, b = 12 , and c = 9

-calculate is called with up to 3 variables.

-If the value of a changes inside the calculate function.,. the value of x will also be changed.

x = 3

y = 10

z = 50

IF(/* condition 1 */) THEN

IF(/* condition 2 */) THEN

PRINTLN "Green is my favorite color!"

PRINTLN "Blue rules!"

ELSE

PRINTLN "All of the rainbow!"

ENDIF

ELSE

x = x * 2

IF(/* condition 1 */) THEN

PRINTLN "All of the rainbow!"

ENDIF

ENDIF

Which of the following can be used to replace /* condition 1 */, /* condition 2 */, and /* condition 3 */ so that the following line is printed:

All of the rainbow!

-/* condition 1 */ /* condition 2 */ /* condition 3 */

x < y (y * 3) < zz <= ((y + 1) / x)

-/* condition 1 */ /* condition 2 */ /* condition 3 */

x > y (y * 3) < zz > x

-/* condition 1 */ /* condition 2 */ /* condition 3 */

(x * 2) < yy < zz >= ((y + 1) / x)

-/* condition 1 */ /* condition 2 */ /* condition 3 */

(x * 2) > yy <= zz >= x

-/* condition 1 */ /* condition 2 */ /* condition 3 */

x <= yy > zz >= x
