TCS Coding Question Day 1 Slot 1 – Question 2

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
