10>commonCharacterCount

Given two strings, find the number of common characters between them. Example For s1 = "aabcc" and s2 = "adcaa", the output should be commonCharacterCount(s1, s2) = 3. Strings have 3 common characters - 2 "a"s and 1 "c".

code>>

int commonCharacterCount(std::string s1, std::string s2) {

int count = 0;

int alphabets[26] = { 0, };

int alphabets1[26] = { 0, };

for (int i = 0; i < s1.size(); i++)

alphabets[s1[i] - 'a']++;

for (int i = 0; i < s2.size(); i++)

alphabets1[s2[i] - 'a']++;

for (int i = 0; i<26; i++)

{

if (alphabets[i] <= alphabets1[i])

count += alphabets[i];

else if (alphabets[i]>alphabets1[i])

count += alphabets1[i];

}

return count;
