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;
    res=(value>>24 & 0x000000FF)|((value>>8)& 0x0000FF00)|((value<<8)& 0x00FF0000)|((value<<24)& 0xFF000000);

    return res;
}

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