hello @dasvishal60

yeah that will work fine but it will do some redundant iterations to reduce that redundant operations we are iterating till j<=n-1-i

when i=1 that means [0…n-1] part is unsorted so our j should go till [0…n-2]
after this iteration n-1 index will get its correct value.
when i=2 that means [0…n-2] part is unsorted so our j should go till [0…n-3]
so on
