 # Easy question

i am not entering into loop after 2nd iteration why it happens ???
help me with this

or

This is the easiest question of the entire set. Just find 6n and print last two digits.

Note : Suppose if your answer is 06 then print just 6.

Input

The first line of the input contains a single integer T (1 ≤ T≤ 10^5) — the number of test cases.

Each test case contains a single line containing single number n . ( 1 <= n <= 10^50 )

Output

Print T lines. In each line print the desired output

mysoultion:

#include <bits/stdc++.h>
using namespace std;

int LastTwoDigit(long long int num)
{

``````int one = num % 10;
num /= 10;
int tens = num % 10;
tens *= 10;
num = tens + one;
return num;
``````

}

// Driver program
int main()
{
int t ;
cin>>t;
while(t–)//it is (t - -) not ( t - )
{
long long int n;
cin>>n;
long long int num = 1;
num = pow(6, n);
cout << LastTwoDigit(num) << endl;

``````}

return 0;
``````

}

Wrong syntax in starting of the while loop, you are supposed to write `while (t—)` (2 minuses) instead of `while (t-)` (one minus)

Its error is formatting here

Observe the constraints on n. It is 10^50. Int or even long long int cannot hold such a large number. So you need to use string. I am not sure, how to find 6^n for such a large number. But if it is 6*N, you can simply use Kasturba’s algorithm for multiplication of string and simply output the last two characters.

I don’t think that we need to apply kasturba’s algorithm over here, it is supposed to be a very easy problem.

question is right
constarints :
The first line of the input contains a single integer T (1 ≤ T≤ 10^5) — the number of test cases.

Each test case contains a single line containing single number n . ( 1 <= n <= 10^50 )

if you have any doubt regarding constraints you can click that link…

yes i think so
we have to use string instead of int

i have written (t - -) only not (t-)

I just executed your solution, it works fine.
Are you using correct input scheme
First line has the number of testcases and the following n lines are the powers of 6.
