Hi , Use Hashing for That , for sum =12 & arr[]={2,4,3,6,5,8,7}; store
in to hashtable & for each index=0 in loop find sum-arr[index] so
fro sum =12 if we do index=1 a[1]=4 & sum-a[1]=8 so stop it we have
done..hope make d perfect code.
time Complxity o(n) space size of hashtable
Let me me if anything wrong ??
