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 high_end = (value >> 16)  & 0xFFFF;

    uint16_t high_hb  = (high_end >> 8) & 0xff;
    uint16_t low_hb  = (high_end) & 0xff;


    uint32_t low_end = (value )  & 0xFFFF;

    uint16_t lowe_hb  = (low_end >> 8) & 0xff;
    uint16_t lowe_lb  = (low_end) & 0xff;
    
    uint32_t low_final =  ( low_hb << 8)| high_hb;
    uint32_t high_final =  ( lowe_lb << 8)| lowe_hb;
   
    return (high_final << 16) | low_final;
}

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