Move zeros to End

 Index Problem is we need to move all the zeros to the right and non-zeros to the left. Move Zeros to End Approaches we can follow are: 1st Approch :  1. Your approach of swapping each 0 element with the end ( j pointer) could work, but it requires some adjustments to handle the indices correctly. However, it’s less efficient than moving the non-zero elements to the front as it repeatedly swaps each 0 with elements toward the end, making it potentially  O ( n 2 ) O(n^2) O ( n 2 ) in the worst case due to unnecessary swaps. Here's a refined version of your approach to help clarify the issues and make it function correctly: Adjusted Code Using End-Pointer Swapping Initialize j to nums.size() - 1 (the last index). Traverse from the beginning, and for each 0 , swap it with nums[j] , then decrement j . However, keep in mind that this will cause the relative order of non-zero elements to change. class Solution { public:     void moveZeroes(vector<int>&...

find the sum of 3 numbers to find next term

This Blog post Describe How to your may find this algorithm else where too. In this Problem Algorithm: We are given a three digits of sequence after that,we need to find the next element in the array,for Example :- [0,2,4] By suming the previous Three Elements,means [0+2+4]=next_term Hence the next term in the array is 6.Now the array is [0,2,4,6]. Intution: Here are the few conditions return mod value of the following sequence. Every time return the sum of last three numbers. def find_nth_term (n) : mod = 10 ** 9 + 7 if n<= 3 : return sequence[n- 1 ] for i in range( 4 ,n+ 1 ): next_term=sequence[- 1 ]+sequence[- 2 ]+sequence[- 3 ]%mod sequence.append(next_term) return sequence[- 1 ] n=int(input()) #Ouput the nth term modulo (10**9+7) result=find_nth_term(n) print(result)
