Doubt in Question 4

#1

can you please explain why the answer is bool and 1 not bool and 0?

@abhinavgoyal912
you can simply write your own comparator for sorting a array.
bool cmp(int a,int b){
return a<b;}

try to return a>b as well,
you will see that If we would like to see a before b in our final sorted ordering then cmp(a, b) should return true value.

no but returning true will mean swap both of them right?and if we swap them then there order is destroyed

#4

Nope returning true means the order will remain same.
A and then B
