Why is min assigned INT_MAX and max assigned INT_MIN?

#1

why is min assigned INT_MAX and mac assigned INT_MIN ?
and how is it working please explain at 2:37

#2

Because we are using min(a, b), max(a, b) operation for this.

#3

Note that this is same as how we initialize s = 0 for sums, because then it doesn’t effect our answer as 0 + anything is = 0.

Similarly for maximum operation, if you initialize with INT_MIN, it won’t affect the answer because everything else is greater than INT_MIN.

but if we assign min = INT_MIN
and max = INT_MAX then its affecting answer and showing undesirable values

#5

Yes, that is expected.

If you initialize with INT_MIN, then there is no other element that is smaller than it, therefore, it will always be INT_MIN.

Similarly for INT_MAX.

Note, that INT_MIN = ‘zero’ of maximum function
same as 0 = ‘zero’ of addition function
