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 b0 = (value & 0x000000ff) << 24;
    uint32_t b1 = (value & 0x0000ff00) << 8;
    uint32_t b2 = (value & 0x00ff0000) >> 8;
    uint32_t b3 = (value & 0xff000000) >> 24;
    return b0|b1|b2|b3;
}

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