Inside The Stadium

Shubman Gill is playing an international match. He played a total of $N$ balls, where, in the $i^{th}$ ball, he scored $A_{i}$ runs. The *strike rate* of a player is calculated as : $\frac{\text{no. of runs}}{\text{no. of balls played}}\times 100$. Preet, a math enthusiast, is currently watching the match. Help him find the number of times, Shubman's *strike rate* became **exactly** $100$. ##
