Factor of 3 Codevita 9 Solution

Problem Description

Given a cluster arr, of size N, discover whether it is conceivable to revamp the components of exhibit with the end goal that total of no two neighboring components is detachable by 3. 

 

Requirements 

 

1 <= T <= 10 

 

2 <= N <= 10^5 

 

1 <= arr[i] <= 10^5 

 

Information 

 

First line contains whole number T signifying the quantity of testcases. 

 

Each experiments comprises of 2 lines as follows- 

 

First line contains number N indicating the size of the cluster. 

 

Second line contains N space isolated numbers. 

 

Yield 

 

For each experiment print either “Yes” or “No” (without cites) on new line. 

 

Time Limit 

 

 

Models 

 

Model 1 

 

Info 

 

 

 

1 2 3 

 

Yield 

 

Truly 

 

Clarification 

 

A portion of the modifications can be {2,1,3,3}, {3,3,1,2}, {2,3,3,1}, {1,3,3,2},… 

 

We can see that there exist at any rate 1 mix {3,2,3,1} where total of 2 contiguous number isn’t separable by 3. Different blends can be {1,3,2,3}, {2,3,1,3}. 

 

Consequently the yield is Yes. 

 

Model 2 

 

Information 

 

 

 

3 6 1 9 

 

Yield 

 

No 

 

Clarification 

 

All conceivable mix of {3,6,1,9} are 

 

{1,3,6,9}, {1,3,9,6}, {1,6,9,3}, {1,6,3,9}, {1,9,3,6}, {1,9,6,3}, 

 

{6,1,3,9}, {6,1, 9,3}, {6,3,1,9}, {6,3,9,1}, {6,9,1,3}, {6,9,3,1}, 

 

{3,1,6,9}, {3,1,9,6}, {3,9,1,6}, {3,9,6,1}, {3,6,1,9}, {3,6,9,1}, 

 

{9,1,3,6}, {9,1,6,3}, {9,3,1,6}, {9,3,6,1}, {9,6,1,3}, {9,6,3,1}. 

 

Since none of these mixes fulfill the condition, the yield is No.
