Minimum Possible value of |ai + aj - k| for given array and k
Minimum Possible value of (ai aj for given array and) is a DSA topic. In plain words you use it for a short Minimum Possible value of ai aj for given array and example in a short dry-run on paper. Don’t start with a slogan — start with that picture.
Smallest example: the smallest Minimum Possible value of ai aj for given array and example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Minimum Possible value of (ai aj for given array and).
From the example next to this theory: Minimum Possible value of |ai + aj - k| for given array and k — arrays give O(1) index access; matrices are arrays of arrays.
Trap: only saying “Minimum Possible value of ai aj for given array and” with no example. Fix that before you talk about advanced DSA.
Viva: what is Minimum Possible value of (ai aj for given array and)? Then show the smallest Minimum Possible value of ai aj for given array and example you can type. Then name the trap.
index → 0 1 2 array → [10, 20, 30]
What is Minimum Possible value of (ai aj for given array and)? Show this: the smallest Minimum Possible value of ai aj for given array and example you can type. Trap: only saying “Minimum Possible value of ai aj for given array and” with no example.
