Question

Problem : Super ASCII String Checker

In the Byteland country a string "S" is said to super ascii string if and only if count of each character in the string is equal to its ascii value.
In the Byteland country ascii code of 'a' is 1, 'b' is 2 ...'z' is 26.
Your task is to find out whether the given string is a super ascii string or not.

Input Format:

First line contains number of test cases T, followed by T lines, each containing a string "S".

Output Format:

For each test case print "Yes" if the String "S" is super ascii, else print "No"

Constraints:
1<=T<=100

1<=|S|<=400, S will contains only lower case alphabets ('a'-'z').


Sample Input and Output

SNo. Input Output
1
2
bba
scca


Yes
No



Explanation:

In case 1, viz. String "bba" -
The count of character 'b' is 2. Ascii value of 'b' is also 2.
The count of character 'a' is 1. Ascii value of 'a' is also 1.
Hence string "bba" is super ascii.

Answer

#include <iostream>
#include <map>
#include <vector>
using namespace std;

int main()
{
int t;
cout<<"Enter the number of cases: ";
cin>>t;
cin.ignore(7777,'\n');
for (int i=0;i<t;i++)
{
string str;
bool b=1;
getline(cin,str);
map<char, int>s;
vector<char>vc;
for (auto c:str)
{
s[c]++;
if (s[c]==1)
vc.push_back(c);
}
for (auto c:vc)
{
if (s[c]!=int(c)-96)
b=0;
}
if (b)
cout<<"Yes"<<endl;
else
cout<<"No"<<endl;
}
