Leetcode Solutions (Array101) in C++

Max Consecutive Ones


Given a binary array nums, return the maximum number of consecutive 1's in the array.


Example1:

Input: nums=[1,1,0,1,1,1]

Output: 3

Explanation: The first two digits or the last three digits are consecutive 1s. The maximum number of consecutive 1s is 3.


Example2:

Input: nums=[1,0,1,1,0,1]

Output: 2

Constraints:

  • 1 <= nums.length <= 105
  • nums[i] is either 0 or 1.

CPP Code:

    int findMaxConsecutiveOnes(vector<int>& nums) {
        int max=0,count=0;
        for (int x: nums)
        {
            if(x==1){
                count++;
                if(count>max)
                    max=count;
            }
            else
                count=0;
        }
        return max;
    }

Removing Odd numbers from a linked list

Deleting odd numbers from a linked list in python: In this program, we will see  how to remove odd numbers from a linked list in Python. This is a very interesting program where we will learn how to remove odd numbers from a linked list. This contains a very easy to understand method of making a linked list. So when you know how to use the linked list we will learn how to remove odd numbers from it. (Note that the program done here is done without using recursion for further simplicity). For removing odd number we first find out the position of the “ head “.  The head is the starting node in a linked list.   Source Code:   class Node:     def __init__(self,data=None,next=None):         self.data=data         self.next=next class SingleLinkedList:          def __init__(self):         self.head=None           def print_list(self):   ...
