Yeah, just as @codename007 said, the statement stated that the number will be positive. I am quite certain, 0000.0000 or 0 is not a positive number. Right?

1 2 e 9 i 8 8 0 ei for this test case your answer outputs 57 it should be 98. also it gives WA for many of the test cases. Try a bit more, you can get it correct.

83

check your code here http://ideone.com/aPoddj
dont u think output should be 100 instead of 0

84

check your code here http://ideone.com/gXgNOa

I am getting wrong answer errorā€¦ please helpā€¦

#include < iostream>
#include < string>

using namespace std;

int main()

int n;
cin>>n;

    int r,counter=0;
    cin>>r;   //  no. of rules.
    char c[r],p[r];
    for(int i=0;i<r;i++)
    {
        cin>>c[i]>>p[i];  // taking each rule as input
    }
    cin>>enPass;  // taking encrypted password as input
    Pass = enPass;
    for(int j=0;j<enPass.size();j++)
    {
        for(int s=0;s<r;s++)
        {
            if(c[s] == enPass[j])
            {

    int str_Size = Pass.size();
    for(int q = str_Size-1; q >= 0; q--)
    {
        if(Pass[q] == '0') Pass.erase(q);
        else if(Pass[q] == '.')
        {
            Pass.erase(q);
            break;
        }
        else break;
    }

   for(int t=0;t<str_Size;t++)

I cracked this after trying different print techniques for the output.
First, I print the op as separate characters(i.e every single S[i] using loop). This didnā€™t work out. Secondly, I print the op as integers(using S[i]-ā€˜0ā€™ except for ā€˜.ā€™). This didnā€™t work out as well. Finally after going through the solution of @pummy02(https://www.codechef.com/viewsolution/7934954) I got a hint. I assigned the 'last+1ā€™th char as null and printed the op as a string. This worked out!

Can somebody help me with this solution, this gives correct answer for all the given tc but on submission gives wa.
