LeetCode: Arrays 101: Introduction - Solutions
LeetCode is a good place to practice programming by solving problems of all levels!
After you solve a problem, you'll get access to all submitted solutions, sorted by time and memory usage. That's a nice way to compare your code to others and see what you did well and where you can improve.
Here's my solutions for the Arrays 101: Introduction card:
Max Consecutive Ones
class Solution: def findMaxConsecutiveOnes(self, nums: List[int]) -> int: max_counter = 0 counter = 0 for i in nums: if i == 1: counter += 1 else: if counter > max_counter: max_counter = counter counter = 0 if counter > max_counter: max_counter = counter return max_counter
Find Numbers with Even Number of Digits
class Solution: @staticmethod def is_even(value): return len(str(value)) % 2 == 0 def findNumbers(self, nums: List[int]) -> int: return_value = 0 for number in nums: if self.is_even(number): return_value += 1 return return_value
Squares of a Sorted Array
When writing code like this be careful because you're altering the A list in place.
class Solution: def sortedSquares(self, A: List[int]) -> List[int]: for index, num in enumerate(A): A[index] = num ** 2 return sorted(A)
