uva 679 - Dropping Balls Solution

uva 679 - Dropping Balls Solution Algorithm: 1. convert (position-1)  to binary and store it to a string. 2. make the binary string length equal to the (depth-1) by adding zero(0) at start of the string. 3. reverse the binary string. 4. convert binary string to integer + power(2,depth-1). Example: depth=7; position=4; covert 4-1= 3 to binary. binary string is 11. make the string length 7-1=6 by adding 0. Updated string 000011. reverse the binary string and string is now 110000 convert binary string(110000) to integer. value is 48. calculate power_value=pow(2,7-1)=pow(2,6)=64. Answer is = 48 + 64=112. Code in C++: #include<iostream> #include<string> #include<algorithm> using namespace std; string convertDecimalToBinary(int num){ string result; while(num!=0){ if(num%2==1) result.insert(0,1,'1'); else result.insert(0,1,'0'); num=num/2; } return result; } int convertBinaryToDecimal(string &n...
