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 res = 0 ;
    res |= (value & 0x000000FF ) << 24;
    res |= (value & 0x0000FF00 ) <<  8;
    res |= (value & 0x00FF0000 ) >>  8;
    res |= (value & 0xFF000000 ) >> 24;
    return res;
}

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