[383] Ransom Note

easy題目，寫開心的XD

bool canConstruct(char * ransomNote, char * magazine){

int *count = calloc(26, sizeof(int));

int magLen = strlen (magazine);

int noteLen = strlen (ransomNote);

for (int i=0;i<magLen;i++)

count[magazine[i]-'a']++;

for (int i=0;i<noteLen;i++)

{

if (count[ransomNote[i]-'a']<=0)

return false;

count[ransomNote[i]-'a']--;

}

return true;

}
