Doubt in return statement

#1

here in if condition he returned a<b and in below statement he returned a.length<b.length.So basically how the comparison is gonna take place, does this mean we already considered that a will be less than b, means I can’t understand how a and b are gonna be compared if we already returned a<b.

hello @aatmictiwari19

let say u pick 2 numbers of array. (say a and b ) note : b comes after a in array.

now in comparator u need to wrtie a logic on how how these two numbers should be there in sorted array.
so if u do return a < b that means u want (smaller elements comes first in array and then bigger elements that is why we have < operator in between a and b)

similarly if u want that bigger element comes first and then smaller element then in such case
u need to do return a> b (i,e i want biiger element comes first and then smaller element that is why > sign).

now try to understand the working of given(in video) comparator based on above logic
