Hii!!

I am getting TLE when I pass a string and its substring’s bounds (low,high) into a function.

And its running good when passing it as a substring.

Here is accepted function…

`ll func(string s,char c) { ll n=s.size(); ll mid=n/2; if(n==1) return (s[0]!=c); ll m1=0,m2=0; for(ll i=0;i<mid;i++) m1+=(s[i]==c); for(ll i=mid;i<=n-1;i++) m2+=(s[i]==c); ll c1=func(string(s.begin(),s.begin()+mid),c+1); ll c2=func(string(s.begin()+mid,s.end()),c+1); return min(n/2-m2+c1,n/2-m1+c2); }`

And here is TLE function…

`ll func(string s,ll low,ll high,char c) { ll n=high-low+1; ll mid=(high-low)/2+low; if(low==high) return (s[low]!=c); ll m1=0,m2=0; for(ll i=low;i<=mid;i++) m1+=(s[i]==c); for(ll i=mid+1;i<=high;i++) m2+=(s[i]==c); return min(n/2-m1+func(s,mid+1,high,c+1),n/2-m2+func(s,low,mid,c+1)); }`

As you can see, the only difference is passing the string.

Please refer to both solutions if any confusion arises…

Can anyone please tell me what I am missing?

NOTE: If this is a problem is related to inline code, please tell me about it as I am not getting how this all is working.
