Given a string, a character, and a count, the task is to print the string after the specified character has occurred count number of times.Print “Empty string” in case of any unsatisfying conditions.(Given character is not present, or present but less than given count, or given count completes on last index). If given count is 0, then given character doesn’t matter, just print the whole string.
Examples:
Input : str = "This is demo string"
char = i,
count = 3
Output : ng
Input : str = "geeksforgeeks"
char = e,
count = 2
Output : ksforgeeks

Implementation:
1- Start traversing the string.
- Increment occ_count if current char is equal to given char.
- Get out of the loop, if occ_count becomes equal to given count.
2- Print the string after the index till the string gets traversed in the loop.
3- If index has reached to the last, then print “Empty string”.
