Set apporach is applicable for non-unique dataset also and unordered map one cannot be used for non-unique nos

#1

just wanna confirm: unordered map approach only valid for uniques numbers did not give right output at : 1,2,2,3,4,5,6,6,7,8

#2

hello @great

for this problem repeation will not matter.

so answer will remain same eithr u use map or set

#3

Hey aman, I am not talking abt the problem mentioned in the video, I am talking abt the case which i mentioned in the question. The unordered map approach should logically fail in the non unique example quoted by me above

#4

answer is 8 and the both will give 8 only.
why u think its wrong?

#5

Hey Aman, see the two codes below
One is the implementation using unordered map by the faculty
second one containing implementation by me of the above logic and using set.
from the codes, i am getting 9 in unordered map and 8 in set (which is the correct answer). also logically if we see then unordered map code does not take into account non-uniqueness
Code1 : https://ide.codingblocks.com/s/486898 (code by faculty)
Code2 : https://ide.codingblocks.com/s/486899 (my implementation of both apporaches)

check now
