For question 2:-
U can use my following code ...
#includeiostream
#includecstdio
using namespace std;
int main()
{
int a[]={4,2,5,2,3,5,1,34,14,64,82,94};
int size=sizeof(a)/sizeof(int);
// printf(%d,size);
for(int i=0;i(int)sqrt(size);i++)printf(%d ,a[i]);
return 0;
}
how can your code ensure.. the top sqrt(N) elements being printed?
for 2nd questions. Its not possible be to do this in less than Linear time..
unless the array has some special property.. (already sorted)

I think it shud be 2*12C6*6C3*6C2
initial 2 is for once we have selected 6 members out of 12, we can either
place them on left side or right side.

got it!
@sagar there shudn be 2's anywhere in the expression.
The different combinations formed on the left hand side by choosing 6 out of
12 will ensure different combinations of other 6 people on the right. So
2*12C6 is not required.
Example:
P1,P3,P5,P7,P9, P11
on left will leave
P2, P4, P6,
yeah
sorry one 2 will be used for either side then auto left and right will be
fixed.
thanks for correction

@sagar there shudn be 2's anywhere in the expression.
The different combinations
the solution will be 12C6* 6c3 * 6C2
because if you choose 6 people for the left side, then there is no option
for the right side(i.e. we can select only the remaining 6 people for right
side)
also this 12C6 will provide all possible combinations for choosing 6 members
for left or right and

is the answer

I hope it can be solved using DP...check my algo below and give any counter
case if you get it...
1. Make an array S equal to the length of the given array where
S[0] = a[0] and S[1] = max(a[0],a[1])
2. for i:2 to n-1
S[i] = max(S[i-2]+a[i], S[i-1])
3. return S[n-1]
Hope
would u please code it for me :)

y+y1=14
