Answer / rohit
Bubble sort with a flag variable to check if comparisons
occur or not. If it is already sorted then in just 1
iteration it will show that the array is sorted which is
not possible in any other sort.THUS JUST 1 ITERATIION IS
REQUIRED IN THIS CASE.

Answer / sathyanarayana
Yes, its insertion sort. For a sorted array, it takes just
O(n) time. iTs mere traversal of an array as it is already
sorted. In the case of quick sort, it boils down to O(n^2)
in the case of sorted array.

Answer / sathya
Insertion sort works with an efficiency of O(n) if the array
is already sorted. Hence, this algo can be used.

Answer / swetha
insertion sort is best one because it takes less time fot sorted array of elements.......

Answer / ronak & sandip
In this case, both insertion and bubble sort will work exactly same as the time complexity of both method is O(n). But you have to mention one condition to check any swap has been made inside or not...if no swap has been made, it will come out of loop after executing it n times.

Answer / soumitra biswas
modified bubble sort with flag.As the array is already sorted
there will be no swapping in first pass,so no comparison
will take place after first pass and program stops executing.
time complexity =0(n).
