Select the correct answerWhat will be the output of the following Python code snippet if x=1?x<<2Options1248

Break Down the Problem

1. Understand the operator: In Python, the << operator is a bitwise left shift operator.
2. Determine the initial value: We know that $x = 1$.

Relevant Concepts

1. Bitwise Left Shift: The left shift operator shifts the bits of the number to the left by the specified number of positions, which effectively multiplies the number by $2^{\text{number of positions}}$.

Analysis and Detail

1. For $x = 1$ and using $x << 2$: $x << 2 = 1 << 2$ This means shifting the binary representation of 1 (which is 0001 in binary) to the left by 2 positions, resulting in 0100 in binary.

   1. The binary 0001 shifts to:
      • Shift 1: 0010 (which is 2)
      • Shift 2: 0100 (which is 4)

Verify and Summarize

1. Therefore, $1 << 2 = 4$.

Final Answer

The output of the code snippet when $x = 1$ is 4.
