Hey @Ankur-Ankur-937479863269311 the reason why we want to deduce ‘0’ from a[i] is because , before deducing ‘0’ the ASCII value of a[i] is in string format but we have to make the ASCII value of a[i] into integer. That’s the reason why we we are deducing’0’ from every element to treat them as an integer value :grinning:
