How is the time complexity o(1)
Time Complexity
This doubt is for Q6 in the quiz.
@ayu_15 hi,vector swap ,swaps the addresses(i.e. the containers exchange references to their data) of two vectors rather than swapping each element one by one which is done in constant time O(1).
lets say
v1 = {1,2,3,4};
v2 = {1,2};
after swapping =>
v2 = {1,2,3,4}
v1 = {1,2}
so v1 and v2 now points to different vector, without accessing the elements of the vector.
