Here is the question :-https://codeforces.net/contest/1270/problem/B
what i understood from the question that we need to find subarrays such that the difference of maximum and minimun element is equal to N (total emenets of array ) ,if it is not possible print "NO" else print "YES" and in next line print 1 and 'ending index' but if we are given an array 'A' and it is statifying condition max(A)-max(B)>=N then according to question answer should be 'YES' 1 N(size of array)
which we even need to check for subarray ?that's all I understood from question please help me out in understanding correctly
here's my code:- ```
include<bits/stdc++.h>
using namespace std;
int main() { int t; cin>>t; while(t--) { int n,f=0; cin>>n;
int A[n],i,j,min=0,max=0,l,r; for(i=0;i<n;++i) { cin>>A[i]; if(max<A[i]) { max=A[i]; //finding max } } min=A[0]; for(i=1;i<n;++i) { if(min>A[i]) { min=A[i]; //finding min } } if(max-min>=n) //checking condition max(A)-min(A)=n { for(i=0;i<n;++i) { if(A[i]==min) //checking at what index is min and max present { l=i+1; //adding 1 in index as index taken from 0 to n-1 } if(A[i]==max) { r=i+1; } } if(l<r) //checking which is greater and printing accordingly { cout<<"YES"<<endl; cout<<l<<" "<<r<<endl; } else { cout<<"YES"<<endl; cout<<r<<" "<<l<<endl; } } else { cout<<"NO"<<endl; } } return 0;
}```
Try the case: 8
1 2 4 0 0 0 0 5
This was my idea as well. It fails on the following test:
1
3
1 3 2
The correct solution checks for every two adjacent numbers if differ by at least 2. If at least two differ by at least 2 (For the test above 1 and 3) print the corresponding positions in the array(For the test above 1 and 2).
Your idea would have printed "NO" instead of "YES endl 1 2".
