NIELIT O Level Exam

To reverse the order of elements in an array, the algorithm must swap elements between:

Array elements को reverse order में rearrange करने के लिए algorithm को किन elements के बीच swap करना चाहिए?

A. Adjacent indices

B. First and last, second and second-last, etc.

C. Random indices

D. Even indices only

Correct Answer is :

B. First and last, second and second-last, etc.
