56. Little Endian to Big Endian

In embedded systems, communication between processors may require byte-order conversion. You are given a 32-bit unsigned integer stored in little-endian format.

Your task is to convert this value to big-endian by swapping its bytes, and print the result.
 

Example-1

Input: 305419896
Output: 2018915346

(0x12345678 → 0x78563412)

Example-2

Input: 1
Output: 16777216

(0x00000001 → 0x01000000)

Example-3

Input: 0xAABBCCDD
Output: 0xDDCCBBAA → 3721182122
