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 ans=0;
    for (int i = 0; i < 4; i++) {
        ans |= ((value >> (8 * i)) & 0xFF) << (8 * (3 - i));
    }
    return ans;

}

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