my code for rainwater harvesting que in array assignment is this can you tell me where i am doing wrong because all the hypothetical case i consider as input, the output is right.
#include
#include
using namespace std;
int main() {
int n;
cin>>n;
int a[n];
for(int i=0;i<n;i++){
cin>>a[i];
}
int hi=0,g;
for(int i=0;i<n;i++){
hi=max(hi,a[i]);
}
for(int i=0;i<n;i++){
if(a[i]==hi){
g=i;
break;
}
}
int sum=0;
int temphi=hi,tempg=g,p;
while(p>0){
int lh=0;
for(int i=0;i<tempg;i++){
lh=max(lh,a[i]);
}
int h;
for(int i=0;i<tempg;i++){
if(a[i]==lh){
h=i;
break;
}
}
for(int i=tempg-1;i>h;i--){
sum=sum+lh-a[i];
}
temphi=lh;
p=h;
tempg=h;
}
tempg=g;
temphi=hi;
while(p<n-1){
int lh=0;
for(int i=tempg+1;i<n;i++){
lh=max(lh,a[i]);
}
int h;
for(int i=tempg+1;i<n;i++){
if(a[i]==lh){
h=i;
break;
}
}
for(int i=tempg+1;i<h;i++){
sum=sum+lh-a[i];
}
temphi=lh;
p=h;
tempg=h;
}
cout<<sum;
return 0;
}
