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 & 0xFF) << 24);
    res |= (((value >> 24) & 0xFF));
    res |= (((value >> 8) & 0xFF) << 16);
    res |= (((value >> 16) & 0xFF) << 8);
    return res;
}

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