Practicing inserting data into an array by using binary search, few problems
- by HelpNeeder
I'm trying to create a method which inserts and then sort elements in form of binary form.
The problem I am experiencing that my code doesn't insert data correctly which means that output does not appear to be in order at all.
The list is not organized, and data is added in order that is being inserted.
Now, 2 questions, what am I doing wrong here? And how to fix this?
public void insertBinarySearch(long value) // put element into array
{
int j = 0;
int lower = 0;
int upper = elems-1;
int cur = 0;
while (cur < elems)
{
curIn = (lower + upper ) / 2;
if(a[cur] < value)
{
j = cur + 1;
break;
}
else if(a[cur] > value)
{
j = cur;
break;
}
else
{
if(a[cur] < value)
lower = cur + 1;
else
upper = cur - 1;
}
}
for(int k = elems; k > j; k--)
a[k] = a[k-1];
a[j] = value;
elems++;
}
