[@chetansahu1505]

Instead of Mid = (lower_limit + higher_limit) /2, applying Mid= lower_limit + (higher_limit - lower_limit)/2 will save the code from throwing error such as integer overflow on higher values of N. Though the video and explaination is commendable. :)

[@millionaireminded4139]

can u plz explain how it will save from throwing such kind of errors??

[@chetansahu1505]

@@millionaireminded4139 yeah sure my pleasure. Definition of Integer overflow : an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits - either higher than the maximum or lower than the minimum representable value (wikipedia) So lets assume for an integer variable x the maximum number it can hold be 15 and any number more than 15 allotted to x would lead to integer overflow. now if we take low = 1, high = 9 so mid = (low+high)/2 and in the worst case low would become 9. low = 9 and high = 9 now x = (low+high)/2 so 9+9 = 18 which is greater than 10 and will lead to integer overflow.( subsequently before 18 divides it by 2 it will throw error cuz 18>15) on the other hand x = low + (high-low)/2 x = 9+ (9-1)/2 x = 9+ (8/2) x = 9+ 4 x = 13 in each step of operation the value of x always remains under 15. This prevents integer overflow error. Hope this helps
