Depend variety of 0’s with given circumstances

Given a binary string (containing 1’s and 0’s), write a program to depend the variety of 0’s in a given string such that the next circumstances maintain:

• 1’s and 0’s are in any order in a string
• Use of conditional statements like if, if..else, and change are usually not allowed
• Use of  addition/subtraction is just not allowed

Examples:

Enter : S = “101101”
Output : 2

Enter : S = “00101111000”
Output : 6

Advisable: Please attempt your strategy on {IDE}  first, earlier than transferring on to the answer.

Method: The above drawback may be solved with the beneath thought:

If counter and conditional statements are usually not allowed. We’re having choice of Error dealing with.

Steps concerned within the implementation of the strategy:

• Take a string and a static variable counter which keep the depend of zero.
• Traverse by means of every character and convert it into an integer.
• Take this quantity and use it as a denominator of the quantity “0”.
• Use the exception dealing with technique attempt..catch in a loop such that every time we acquired the Arithmetic exception, the counter will increment.
• Print the counter worth consequently.

Under is the implementation of the above strategy:

Time Complexity: O(N)
Auxiliary Area: O(1)
