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 be_value = value << 24;
    be_value |= (value & 0xff00) << 8;
    be_value |= (value & 0xff0000) >> 8;
    be_value |= value >> 24;

    return be_value;
}

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