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.

Answer 1

Solve
#include <iostream>

int main()
{
char str[100];
std::cout<<"Input string: ";
std::cin>>str;

int i=0;
//calculate number of symbols:
int numbers[26]={0};
while(str[i]!='\0')
{
if((str[i]>='a')&&(str[i]<='z'))
numbers[str[i]-'a']++;
i++;
}
//check numbers and number in super ascii:
int isAscii=1;
for(i=0;i<26;i++)
if((numbers[i]>0)&&
(numbers[i]!=(i+1)))
{
isAscii=0;
break;
}
if(isAscii==0)
std::cout<<"No";
else
std::cout<<"Yes";

return 0;
}
