Answer:
integer = [1, 2 , 4 , 6, 7, 9, 9]
integer.sort()
n = len(integer)
if n == 0 or n == 1:
print (n)
b = 0
for i in range(0, n-1):
if integer[i] != integer[i+1]:
integer[b] = integer[i]
b += 1
integer[b] = integer[n-1]
b += 1
print (b)
Step-by-step explanation:
The code is written in python
integer = [1, 2 , 4 , 6, 7, 9, 9]
The list that takes the list of integers
integer.sort()
The list integer is sorted .
n = len(integer)
The length of the list of integer is gotten.
if n == 0 or n == 1:
If the length is equal to 0 or 1
print (n)
The the length
b = 0
We equate b to 0
for i in range(0, n-1):
The "for loop" loops through 0 to length of the list - 1
if integer[i] != integer[i+1]:
if the index value in the list is not equals to the next index value in the list
integer[b] = integer[i]
The index value b is equal to index value of the looped item.
b += 1
then add 1 to b
integer[b] = integer[n-1]
The index value of b = index value of the length - 1.
b += 1
then add 1 to b
print(b)
print the value of b which is the length of the new list.
