Code

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

uint32_t convert_endian(uint32_t value) {
    
    uint32_t val = 0;
    
    val |= ((value & 0xff000000) >> 24) << 0;
    val |= ((value & 0x00ff0000) >> 16) << 8;
    val |= ((value & 0x0000ff00) >> 8) << 16;
    val |= ((value & 0x000000ff) >> 0) << 24;

    return val;
}

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