Hello,
<< (left shift) Takes two numbers, left shifts the bits of the first operand, the second operand decides the number of places to shift. Or in other words, left shifting an integer āxā with an integer āyā (x<<y) is equivalent to multiplying x with 2^y (2 raised to power y)
<< have left to right associativity so 5<<2 is evaluated then (5<<2)<<5 is evaluated
First 5 is converted to binary and 2 bit is shifted to left so the answer is 20 then 20<<5 is performed so the answer is 640
