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

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