Given sorted array [2,4,6,8,10], using two pointers to check if any pair sums to 7, what is the result?

Question

Accepted Answer

(B) No such pair exists. Explanation: Pairs attempted: (2,10)=12>7 → right--. (2,8)=10>7 → right--. (2,6)=8>7 → right--. (2,4)=6<7 → left++. (4,6) no longer... (4,4)? Left=right, stop. No pair found.
