# Result from Test comes out different to edit view result with the same input.

• I have a solution that gets the correct result when tested against the test interface but the wrong answer when actually running against the test cases. I attached a picture. Does anyone have this issue too ?
By doing this one by hand, I get 3 as my algorithm calculates as well.

Either way here is my solution:

``````typedef pair<int, int> envelope;

bool operator > ( envelope& env1, envelope& env2 )
{
return (env1.first > env2.first) && (env1.second > env2.second);
}

class Solution
{
public:

int maxEnvelopes( vector<envelope>& envelopes )
{
size_t len = envelopes.size();
if( !len )
return 0;

if( len == 1 )
return 1;

sort( envelopes.begin(), envelopes.end());
envelope inner_most;
envelope base;
bool first_fit = false;
int cnt_RL = 0;
int cnt_LR = 0;
int i, j;

// first find first pair
for( i = len-1; i > 0; --i )
{
for( j = i-1; j > 0; --j )
if( envelopes[i] > envelopes[j] )
{
cnt_RL+=2;
first_fit = true;
inner_most = envelopes[j];
j--; // keep track of inner_most envelope
break;
}
if( first_fit )
break;
}

if( !cnt_RL )
return 1;

// find rest that fit
for( int k = j; k >= 0; --k )
{
if(  inner_most > envelopes[k] )
{
cnt_RL++;
inner_most = envelopes[k];
}
}
// end RL to left portion
first_fit = false;

// begin LR portion
for( i = 0; i < len-1; ++i )
{
for( j = i+1; j < len-1; ++j )
if( envelopes[j] > envelopes[i] )
{
cnt_LR+=2;
first_fit = true;
base = envelopes[j];
i++; // keep track of base envelope
break;
}
if( first_fit )
break;
}

if( !cnt_LR )
return 1;

// find rest that fit
for( int k = i; k <= len-1; ++k )
{
if( envelopes[k+1] > base )
{
cnt_LR++;
base = envelopes[k+1];
}
}
if( cnt_LR >= cnt_RL )
return cnt_LR;
return cnt_RL;
}

void display( std::vector<envelope>& envs )
{
for(auto& el : envs )
{
std::cout << " (" << el.first << ", " << el.second << "), ";
}std::cout << std::endl;
}
};
