If 777 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 0001100001001 in which the leftmost bit is the sign bit, followed perhaps by more trailing 0’s, and then by magnitude bits.

The reason to have the binary 777 signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 777 signed using two’s complement, will start with one or more 1’s, but the exact code for -777 decimal to binary depends on the signed number representation system and number of bits available.
