Just learning Bitwise Shift Operators.
The easiest way to resolve a bitwise shift operators is my multiply or dividing each step by two
for left shift or right shift respectively
Example:
LEFT SHIFT
echo 8 << 3; //16
//same as
echo 8 * 2 * 2 * 2;
RIGHT SHIFT
echo 8 >> 3; //1
//same as
echo ((8/2)/2)/2; //1
//Solving on a paper 8/2 = 4/2 = 2/2 = 1
