Problem with my code for flames game

This is my code in matlab for flames game but unable to get expected output.

Please check the code and help me to solve the problem

In this i am comparing two strings and replacing matching charaecters with '/' and also counting and at the end counting the number(n) of remaining charaecters other than '/' and incrementing pointer for flames string until n becomes zero for five times and replacing all such charecters in flames with '/'

p=input('Enter the first string:'); o=input('Enter the second string:'); c=size(p,2); d=size(o,2); for i=1:c for j=1:d if(p(i)==o(j)) p(i)='/'; o(j)='/'; else disp('Do_nothing'); end end end f=0; for i=1:c if(p(i)~='/') f=f+1; else disp('Do_nothing'); end end q=0; for j=1:d if(o(j)~='/') q=q+1; else disp('Do_Nothing'); end end handles.g=f+q; n=0; h='FLAMES'; for m=1:handles.g n=n+1; end v=n; i=1; for v=1:5 while(n) if(n>1) n=n-1; if(h(i)~='S') i=i+1; elseif(h(i)=='S') i=0; elseif(h(i)=='/') i=i+1; n=n+1; end end if(n==1) if(h(i)~='S') i=i+1; elseif(h(i)=='S') i=0; elseif(h(i)=='/') i=i+1; n=n+1; end end end W=regexprep(h,'h(i)','/'); end %disp('So the relationship between you has:'); %k;

Thanks in advance.

Try this

function Match=FLAMES(nm1,nm2)

letter2number = @(c)1+lower(c)-'a';

A=letter2number(nm1);

B=letter2number(nm2);

C=[];

for i=1:length(A)

z=find(A(i)==B);

if length(z)>0

B(z(1))=[];

C=[C i] ;

end

end

R=(length(A)-length(C))+length(B);

Match='FLAMES';

for i=1:5

s=mod(R,7-i);

if s==0

Match(end)=[];

else

Match(s)=[];

end

end

return

Example

Match=FLAMES('sivakumar','indhu')

Output

Match =

'A'
