An exciting question asked in recent quant interview round by Da Vinci in IITB this year
Wanted to share another solution, considering the min and max value of X we have:
X_min => when K = 8 then X_min = 11111111
X_max => when K = 0 then X_max = 99999999
as to calculate the expected value we can simply find the average of the 2 extreme values
E[X] = (11111111 + 99999999) / 2 = 55555555
let me know if this helps 😊
its perfect
