Little Endian to Big Endian

Code

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

uint32_t convert_endian(uint32_t val) {
    // Write logic to swap bytes
    int j=24; 
    uint32_t ans=0;
    for(int i=0;i<4;i++){
       ans|=((val<<j)&0xff000000)>>i*8;
       j-=8;

    }
    return ans;
}

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