Ans. Brute force
The key here is to traverse all the lines sequentially, and for each line, we print the required character at the given index.
The steps are as follows:
• We will define matrix ‘ans’ to store the final pattern.
• We will initialize a variable ‘k’ to 1, which will be the starting value for the pattern.
• We will iterate over all the rows, i.e., i = 0 to i = N - 1:
  • We will run a for loop starting from j = N - i -1 with t...read more

Ans. Brute Force Approach
Approach: We will recursively find all possible permutations and then check for each of them whether it is following the condition or not.
 
We will maintain a counter based on that and increment it when the current permutation satisfies the condition.
 
Algorithm :  
 
// It is a recursive function to get all the permutations of the current array 'arr'.
void getPermutations(arr, i...read more

Ans. 
Declare a character stack S.
Now traverse the expression string exp. 
If the current character is a starting bracket (‘(‘ or ‘{‘ or ‘[‘) then push it to stack.
If the current character is a closing bracket (‘)’ or ‘}’ or ‘]’) then pop from stack and if the popped character is the matching starting bracket then fine else brackets are not balanced.
After complete traversal, if there is some starting bracket left in stac
