This code also doesn’t work and has many syntax errors
hi @muskanrathore01_4aab76aa7dafc189
i don’t think there is any syntax errors in the code i shared as it is working fine… also i tried the code on all the 3 test cases individually, its working fine and giving the correct o/p… if still on submission it shows error, then there might be some compiler issues…
This is the error it is showing: #include<iostream> | ^ main.cpp:9:9: error: #include expects “FILENAME” or 9 | #include<vector> | ^ main.cpp: In function ‘int main()’: main.cpp:13:5: error: ‘cin’ was not declared in this scope 13 | cin>>n; | ^~~ main.cpp:1:1: note: ‘std::cin’ is defined in header ‘’; did you forget to ‘#include ’? +++ |+#include 1 | /****************************************************************************** main.cpp:13:9: error: ‘gt’ was not declared in this scope 13 | cin>>n; | ^~ main.cpp:14:5: error: ‘vector’ was not declared in this scope 14 | vector<int> v; | ^~~~~~ main.cpp:1:1: note: ‘std::vector’ is defined in header ‘’; did you forget to ‘#include ’? +++ |+#include 1 | /****************************************************************************** main.cpp:14:12: error: ‘lt’ was not declared in this scope 14 | vector<int> v; | ^~ main.cpp:14:23: error: ‘v’ was not declared in this scope 14 | vector<int> v; | ^ main.cpp:15:23: error: expected ‘)’ before ‘;’ token 15 | for(int i=0;i<n;i++){ | ~ ^ | ) main.cpp:15:24: error: ‘i’ was not declared in this scope 15 | for(int i=0;i<n;i++){ | ^ main.cpp:25:23: error: ‘gt’ declared as reference but not initialized 25 | vector<int> temp = v; | ^~ main.cpp:25:27: error: ‘temp’ was not declared in this scope 25 | vector<int> temp = v; | ^~~~ main.cpp:26:27: error: expected ‘)’ before ‘;’ token 26 | for(int i=0;i<n;i++){ | ~ ^ | ) main.cpp:33:23: error: expected ‘)’ before ‘;’ token 33 | for(int i=0;i<n;i++){ | ~ ^ | ) main.cpp:36:5: error: ‘cout’ was not declared in this scope 36 | cout<<sum<<endl; | ^~~~ main.cpp:36:5: note: ‘std::cout’ is defined in header ‘’; did you forget to ‘#include ’? main.cpp:36:28: error: ‘endl’ was not declared in this scope 36 | cout<<sum<<endl; | ^~~~ main.cpp:1:1: note: ‘std::endl’ is defined in header ‘’; did you forget to ‘#include ’? +++ |+#include
ok the code you gave earlier in text was coming in this format:
#include<iostream>
#include<vector>
using namespace std;
int main() {
int n;
cin>>n;
vector<int> v;
for(int i=0;i<n;i++){
int no;
cin>>no;
v.push_back(no);
}
int q;
cin>>q;
while(q--){
int x;
cin>>x;
vector<int> temp = v;
for(int i=0;i<n;i++){
temp[i] = v[i] + v[(i-x+n)%n];
}
v = temp;
}
long long int sum = 0;
for(int i=0;i<n;i++){
sum = (sum + v[i])%1000000007;
}
cout<<sum<<endl;
}
This image one is working fine. Btw can you explain what was the main error in my original code?hi @muskanrathore01_4aab76aa7dafc189
Actually i couldn’t make out our logic… this was a simple code and main part was just
temp[i] = v[i] + v[(i-x+n)%n];
