WebfitsBits(x,n) Return 1 if x fits in an n-bit two’s complement int, 2 : 15 : otherwise, return 0 : addOK(x,y) Return 1 if x+y can be computed : 3 : 20 : without overflow, otherwise, return 0 ... */ int sign(int x) We can easily replicate sign bit by doing: x>>31 = 0x0 if x>=0; x>>31 = 0xffffffff=-1 if x<0 We are close now. We need to get 0x1 ... WebMar 16, 2024 · Method 1. There can be overflow only if signs of two numbers are same, and sign of sum is opposite to the signs of numbers. 1) Calculate sum 2) If both numbers are positive and sum is negative then return -1 Else If both numbers are negative and sum is positive then return -1 Else return 0.
