Problem Statement – Given a string S(input consisting) of ‘*’ and ‘#’. The length of the string is variable. The task is to find the minimum number of ‘*’ or ‘#’ to make it a valid string. The string is considered valid if the number of ‘*’ and ‘#’ are equal. The ‘*’ and ‘#’ can be at any position in the string. Note : The output will be a positive or negative integer based on number of ‘*’ and ‘#’ in the input string. (*>#): positive integer (#>*): negative integer (#=*): 0 Example 1: Input 1: ###***   -> Value of S Output : 0   → number of * and # are equal    Solution in C++   #include < bits / stdc ++. h > using namespace std ; int main () { string s = "Hello" ; int a = 0 , b = 0 ; getline ( cin , s ); for ( auto i : s ) if ( i == '#' ) a ++; else if ( i == '*' ) b ++; cout << b - a ; }      Solution in Java   import java . ut...

Problem Statement – An automobile company manufactures both a two wheeler (TW) and a four wheeler (FW). A company manager wants to make the production of both types of vehicle according to the given data below: 1st data, Total number of vehicle (two-wheeler + four-wheeler)=v 2nd data, Total number of wheels = W The task is to find how many two-wheelers as well as four-wheelers need to manufacture as per the given data. Example : Input : 200  -> Value of V 540   -> Value of W Output : TW =130 FW=70 Explanation: 130+70 = 200 vehicles (70*4)+(130*2)= 540 wheels Constraints : 2<=W W%2=0 V<W Print “INVALID INPUT” , if inputs did not meet the constraints. The input format for testing  The candidate has to write the code to accept two positive numbers separated by a new line. First Input line – Accept value of V. Second Input line- Accept value for W. The output format for testing  Written program code should generate two outputs, each separated by a single ...
