Hey @Nidhi_Alipuria
your answer is overflowing
Here I updated it

#include<iostream>
using namespace std;

long long calculate(int n,long long dp[])
{
if(n==0)
return 1;
if(n==1)
return 2;
if(dp[n]!=0)
return dp[n];

long long a=calculate(n-1,dp);
long long b=calculate(n-2,dp);
//cout<<a<<b<<" ";
return dp[n]=a+b;

}

int main()
{
int test;
cin>>test;
long long dp[100]={0};
while(test–)
{
int n;
cin>>n;
calculate(n,dp);
cout<<dp[n]<<endl;
}
}
