O(NlogN)

Explanation:

The time complexity of quick sort in worst case is O(N²) but the average case time complexity of quick sort is O(NLogN).The efficiency of quick sort totally depends upon the pivot.If the pivot is the smallest or the largest element in the array every time then the time complexity of quick sort algorithm will come out to be O(N²).

Obtain the 10’s complement of the following six-digit decimal numbers:<br><br> 123900<br><br> 980657
zysi [14]

Answer:

876100

019343

Explanation:

10s complement of a decimal number is obtained by the following process:

- Obtain 9s complement ( Subtract each digit by 9)

- Add 1 to the result

1) 123900

9s complement => (9-1)(9-2)(9-3)(9-9)(9-0)(9-0)

= 876099

Adding 1 , 10s complement of 123900 = 876100

2) 980657

9s complement = (9-9)(9-8)(9-0)(9-6)(9-5)(9-7)

= 019342

Adding 1 , 10s complement of 980657 = 019343

zepelin [54]

Answer:

\textsf{\large{\underline{Solution}:}}

The given problem is solved using language - Python.

def f(x):

   new_list=[]

   for i in x:

       if i%2==0:

           new_list.append(i//2)

       else:

           new_list.append(i*2)

   return new_list

   

my_list=list(range(1,6))

print('Original List:',my_list)

my_list=f(my_list)

print('Modified List:',my_list)

\textsf{\large{\underline{Logic}:}}

  1. Create a new list.
  2. Iterate over the list passed into the function.
  3. Check if the element is even or not. If true, append half the value of element in the list.
  4. If false, append twice the value of the element in the list.
  5. At last, return the new list.

There is another way of doing this - By using map() function.

—————————————————————————————

def f(x):

   return list(map(lambda x:x//2 if x%2==0 else 2*x,x))

   

my_list=list(range(1,6))

print('Original List:',my_list)

my_list=f(2my_list)

print('Modified List:',my_list)

—————————————————————————————

\textsf{\large{\underline{O{u}tput}:}}

Original List: [1, 2, 3, 4, 5]

Modified List: [2, 1, 6, 2, 10]
