Instead of rotating each element we can just cut the string upto that index and paste(append) it at the end of the string.
A solution for python would be
def leftrotation(a,d): return(a[d:]+a[:d])
beautiful solution!!!
but this will not work when d > len(a)
Correct, I added this line first to account for cases when d > len(a).
d = d % len(a) if d > len(a) else d
You don't need the if statement here. It's the same as writing: d = d % a
true, but the constraints say 1 <= d <= n :)
