Popular Questions

#Question 1

Suppose you are given a sequence of N different types of fruits arranged in a row, where each fruit represents a type of dish. Your task is to find the maximum number of fruits you can pick while satisfying the following conditions:

  • You can only pick one type of fruit.
  • You cannot pick two adjacent fruits of the same type.

What type of fruit should you choose to achieve the maximum number of fruits?

#Question 1

Given a positive integer N, write a function to determine the number of bases between 2 and N (inclusive) in which the representation of N starts with the digit 1.

#Solution 1

```sh

def count_bases(N: int) -> int:

count = 0

for base in range(2, N+1):

if int(str(N)[0]) == 1:

count += 1

return count

```

#Question 2

Given a list of positive integers, write a function to find the number of bases in which the representation of each integer in the list starts with the digit 1.

#Solution 2

```sh

def count_bases_list(lst: List[int]) -> int:

count = 0

for num in lst:

for base in range(2, num+1):

if int(str(num)[0]) == 1:

count += 1

return count

```

#Question 2

You are given three stacks of blocks, where the first stack contains A blocks, the second stack contains B blocks, and the third stack contains C blocks. Your task is to determine if it is possible to move blocks from one stack to the other two stacks such that the final two stacks have X and Y blocks, respectively. To move the blocks, you must choose one stack, take some number of blocks from it, and move them to the other two stacks, such that one stack has k blocks and the other stack has s-k blocks.

#Question 3

Given a string that represents a number in a certain base, write a function to determine the next number in the sequence that starts with 1 in that base.

#Solution 3

```sh

def next_num_base(s: str, base: int) -> str:

num = int(s, base)

while True:

num += 1

if str(num)[0] == "1":

return str(num)

```

#Question 3

Altaf has recently learned about number bases and is becoming fascinated.

Altaf learned that for bases greater than ten, new digit symbols need to be introduced, and that the convention is to use the first few letters of the English alphabet. For example, in base 16, the digits are 0123456789ABCDEF. Altaf thought that this was unsustainable; the English alphabet only has 26 letters, so this scheme can only work up to base 36. But this is no problem for Altaf, because Altaf is very creative and can just invent new digit symbols when she needs them. (Altaf is very creative.)

Altaf also noticed that in base two, all positive integers start with the digit 1! However, this is the only base where this is true. So naturally, Altaf wonders: Given some integer N, how many bases b are there such that the base-b representation of N starts with a 1?

#Question 4

Given an integer N, write a function that returns all the bases between 2 and N inclusive for which representation of N starts with the digit 1

#Solution 4

```sh

def bases_with_1(N: int) -> List[int]:

res = []

for base in range(2, N+1):

if int(str(N)[0]) == 1:

res.append(base)

return res

```

#Question 5

Given a List of integers and a target integer x, write a function that returns the number of bases between 2 and x inclusive for which representation of each element in the list starts with the digit 1

# Solution 5

```sh

def count_bases_list_and_target(lst: List[int], x: int) -> int:

count = 0

for num in lst:

for base in range(2, x+1):

if int(str(num)[0]) == 1:

count += 1

return count

```
