Little Endian to Big Endian

Code

#include <stdio.h>
#include <stdint.h>

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    uint32_t result;
    result = (value & 0xFFFF)<<16 | ((value>>16) & 0xFFFF);
    // printf("%x\n",result);
    result = (result & 0xFF000000)>>8 | (result & 0x00FF0000)<<8 | (result & 0xFF00)>>8 | (result &0xFF)<<8;
    // printf("%x\n",result);
    return result;
}

int main() {
    uint32_t val;
    scanf("%u", &val);
    printf("%u", convert_endian(val));
    return 0;
}
