If second operand is -ve in a shift operator
How the bit will be shifted?
Eg : 2>>-1

2 >> -1

Bit pattern of 2 = 00000010
Bit pattern of -1 = 11111111

If the shift distance value is greater than 32, the least five digits are taken as the shift distance. Here, the least five digits of the bit pattern of -1 is taken as the shift distance. Therefore, the shift distance becomes 31 (11111).

So, 2 >> 31 = 0.

Hope you get it!!
