//输入一个10进制数，一个负进制，输出转化后的数字

#include <bits/stdc++.h>

    'P','Q','R','S','T',
    'U','V','W','X','Y','Z'

    while(scanf("%d%d",&n,&base) != EOF){
        printf("%d=",n);
        while(n != 0){
            k = n % base;
            t = n / base;
            if(k < 0){
                k -= base;
                t ++;
