为什么C++能过，G++不能过？这一题的数据量比较大，确实难入手

#include<cstdio>#include<algorithm>using namespace std;const int MAX = 1000010;typedef struct _Node{introw;intcol;intvalue;}Node;intArray[MAX];NodeInput[500010];introwdata[500010];intcoldata[500010];introw,col,n;boolcmprow( const Node & left , const Node & right ){return left.row < right.row;}voidcreaterowmap(){sort( &Input[0] , &Input[n] , cmprow );int begin = 0 ;row = 0 ;for( int i = 0 ; i != n ; ++i )if( Input[i].row != Input[begin].row ){rowdata[ row ] = Input[ begin ].row;row++;begin = i ;}rowdata[ row ] = Input[ begin ].row;row++;}boolcmpcol( const Node & left , const Node & right ){return left.col < right.col;}voidcreatecolmap(){sort( &Input[0] , &Input[n] , cmpcol );int begin = 0 ;col = 0 ;for( int i = 0 ; i != n ; ++i )if( Input[i].col != Input[begin].col ){coldata[ col ] = Input[ begin ].col;col++;begin = i ;}coldata[ col ] = Input[ begin ].col;col++;}intbinarysearch( int * a , int left , int right , int key ){int middle;while( left <= right ){middle = ( left + right )/2;if( a[ middle ] == key )return middle;else if( a[middle] < key )left = middle + 1 ;elseright = middle - 1 ;}return -1;}int main(){int place1 , place2;scanf("%d",&n);for( int i = 0 ; i != n ; ++i )scanf("%d%d%d",&Input[i].col , &Input[i].row , &Input[i].value );createrowmap();createcolmap();for( int i = 0 ; i != n ; ++i ){place1 = binarysearch( rowdata , 0 , row - 1 , Input[i].row );place2 = binarysearch( coldata , 0 , col - 1 , Input[i].col );Array[ place1 * col + place2 ] += Input[i].value;}printf("-1");for( int i = 0 ; i != col ; ++i )printf(" %d",coldata[i]);printf("/n");intk = 0 ;for( int i = 0 ; i != row ; ++i ){printf("%d",rowdata[i]);for( int j = 0 ; j != col ; ++j )printf(" %d",Array[k++]);printf("/n");}return 0;}
