I need help: regarding modulo and array shifting
Hi Codeforces Friends, I was recently doing an array shift left problem and I was trying to use modulo to achieve that. However, I wasn't able to derive a general formula for it, and I try this in both the 0-index way and the 1-index way. Do you guys have any idea?
ex: k — the number of times to shift left A — the array
output the final array after k times shifting left
