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 = 0;
    int mul = 8;
    for (int i = 0; i < 4; i++){
        res <<= 8;
        res |= value & 0xFF;
        value >>= 8; 
    }
    return res;
}

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