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 ans = ((value&0xFF) << 24) | ((value & 0xFF000000) >> 24);
    ans = ans | (((value &  0xFF0000) >> 8) | ((value & 0xFF00) << 8) );
    return ans;
}

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