Answer 1

def char_to_uppercase(s, idx) : 
    length = len(s) 
    if (idx < 0 or idx > length): return s
    s = list(s)
 
    for i in range(length) : 
        if (i == idx and (ord(s[i]) >= 97 and ord(s[i]) <= 122)):
            s[i] = chr(ord(s[i]) - 32)
    
    return "".join(s)
  
  
  
s = "python programming"
      
s = char_to_uppercase(s, 4)
print(s)
      
s = char_to_uppercase(s, 0);
print(s)
       
s = char_to_uppercase(s, len(s) - 1);
print(s)
