how shell we know that the given no is negative as its ans is -1 and it could be also around 2055 in dercimal but how we know that it is in 2s complement notation
Regarding the no 11111111111
Hey @Pranjul see the main idea behind this is to store negative nos in binary we simply use the leftmost bit of the number as a special value to represent the sign of the number : 0 = positive, 1 = negative . For example, a value of positive 12 (decimal) would be written as 000…1100 in binary , but negative 12 (decimal) would be written as 100…1100.
