A simple code
#include
using namespace std;
int main() {
int t,g,i,n,q;
cin>>t;
while(t–){
cin>>g;
while(g–){
cin>>i>>n>>q;
if(n%2==0){
cout<<n/2<<endl;
}else{
if(i==q){
cout<<n/2<<endl;
}else{
cout<<(n/2)+1<<endl;
}
}
}
}
return 0;
}
this my code and it works perfectly fine in custom inputs without any problem , but during the submission it shows time limit exceeded.
MY CODE:-
T = int(input())
for i in range(1,T+1):
G = int(input())
for u in range(1,G+1):
I,N,Q = input().split()
I = int(I)
N = int(N)
Q = int(Q)
k = 1
mylist = list()
for z in range(0,N):
mylist.append(I)
for i in range(0,N):
for j in range(0,k):
if (mylist[j] == 1):
mylist[j] = 2
else:
mylist[j] = 1
k = k + 1
if (Q == 1):
count = mylist.count(Q)
print(count)
else:
count = mylist.count(Q)
print(count)
i have written according to what i understood…the code runs fine and gives correct output but at time of submission it shows Time limit exceeded ! How can i optimize it!
#include <iostream>
#include<algorithm>
using namespace std;
int getGuesses(int init, int n, int q) {
int arr[n];
int count=0;
fill_n(arr + 1, n, init);
for(int i=1; i<=n; i++) {
for(int j=1; j<=i; j++) {
arr[j] = (arr[j]%2==0) ? 1 : 2;
}
}
for(int i=1; i<=n; i++) {
if(arr[i]==q) {
++count;
}
}
return count;
}
int main() {
ios_base::sync_with_stdio(false);
cin.tie(NULL);
int test, g, ini, n, q, count=0;
cin >> test;
while(test--) {
cin >> g;
while(g--) {
cin >> ini >> n >> q;
count = getGuesses(ini, n, q);
cout << count << "\n";
}
}
return 0;
}
