Make a program that:

1. counts the number of occurrence of a character (regardless of its case) from a given string:

Example Input/Output1:
Input any string: thE five boxing wIzards jump quIckly.
Character to check: i
Number of occurrence for i: 4

Example Input/Output2:
Input any string: thE five boxing wIzards jump quIckly.
Character to check: e
Number of occurence for e: 2

2. gets the sum of all the numbers (positive numbers only) found from a given string:

Example Input/Output1:
Input any string: th3 f1v3 b0x1n-6 w1z4rd5 jump qu-1ckly.
Sum of all digits from the string: 25

Example Input/Output2:
Input any string: C#3ck 4ll d d1g1ts fr0m th15 57r1n6 @nd 637 d 5um d0n3!
Sum of all digits from the string: 58

Example Input/Output3:
Input any string: 7-4-1982
Sum of all digits from the string: 31

3. inputs a string and converts the string in Title Case.

Example Input/Output:
Input any string: the quick brown fox jumps over the lazy dog.
String in title case: The Quick Brown Fox Jumps Over The Lazy Dog.

4. inputs a string and converts the string in reverse titlE casE.

Example Input/Output:
Input any string: the five boxing wizards jump quickly
String in title case: thE fivE boxinG wizardS jumP quickly

5. finds and replaces a character (regardless of its case) from a given string.

Example Input/Output:
Input any string: Programming is so boring.
Find character: o
Replace with: x

Result after replacing o with x: Prxgramming is sx bxring.

6. inputs a series of strings and counts the number of strings where the string length is 3 or more and has the same  character (regardless of its case) on both ends.

Example Input/Output:
Number of elements to check: 6
String1: aa
String2: xyx
String3: sleep eat love
String4: Eddie Vedder’s collections are extremely rare
String5: first 2nd 3rd 4th
String6: abc xyz cbA

Found 3 string(s) having the same character on both ends.
