Little Endian to Big Endian

Code

#include <stdio.h>
#include <stdint.h>

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    int n=4;
    uint32_t result=0;
    while(n--){
        result=result<<8;
        result |= (value & 0xFF);
        value=value>>8; 
    }
    return result;
}

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