Hi…In Find Me Problem it has to be said that a set of numbers will be inputted and a desired number will also be inputted to verify that it is among that array of number. If that desired number is present print 1 otherwise -1.
My code is given below…whats the problem with my code,
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,i,c[100],d=0,first,last,mid;
cin>>a>>b;
for(i=1;i<=a ;i++)
{
cin>>c[i];
}
for(i=1;i<=a ;i++)
{
first=1;
last=a;
while(first<=last)
{
mid=(first+last)/2;
if(b==c[mid])
{
d=1;
break;
}
else if(b<c[mid])
{
last=mid-1;
}
else
{
first=mid+1;
}
}
}
if(d==0)
{
cout<<"-1"<<endl;
}
else
cout<<“1”<<endl;
}
i have found it clear and no problem in finding correct output. Although the submission judge said answer is wrong. PLzzz help me
