We'll simulate the battle while maintaining two variables: Mario's current HP (initially $50$ ~50~), and the number of Life Shrooms $L$ ~L~ consumed so far (initially $0$ ~0~). Upon inputting each value $H_i$ ~H_i~, we should first increase HP by $H_i$ ~H_i~ (setting it equal to $50$ ~50~ if it would exceed $50$ ~50~). Then, if HP $\le 0$ ~\le 0~, we should set it equal to $10$ ~10~ and increment $L$ ~L~ by one. After processing all $N$ ~N~ events in this manner, we can output $L$ ~L~.
