for(int i = 0 ; i<temp.length;i++) {
if(temp[i]==replace) {
temp[i]=(char) (count+49);
count++;

}
this can also be done since ascii of 1 is 49

Nice. Kindly give data structure video also

[YashSingh-xsyj]

Sir, it was a great tutorial can you please help, one interview coding question which was based on String I was not able to solve that properly
Input: abbcccdddd
Output: ab2c3d4
If the repetition of a char in a string is more than one, then it should be replaced by a number denoting the occurrence of that char in String

9:05 why this will not work, not clear, does it mean it will store only single char of integer like not greater than 0-9 ?

[sainath]

string str = "opentext";
char ch = 't';
int count = 48;
char[] chars = str.ToCharArray();
for (int i = 0; i < chars.Length; i++)
{
if (ch == chars[i])
{
count++;
chars[i] = (char)count;
}
}
Console.WriteLine(chars);

[beastcombatanalysing]

What would happen if we just did it as arr[i] = String.valueOf(cnt); ?

[ajayghode]

Thank you sir..

I'm facing issue with
if (input.indexOf(charToReplace == -1)) is not working...

Error: The method indexOf(int) in the type String is not applicable for the arguments (boolean)
Any one can help me with this plz..
Thanks

[YashSingh-xsyj]

package StringQuestions;

public class {

public static void main(String[] args) {
String input = "opentext";
char chCheck = 't';

input = input.toLowerCase();

if (input.indexOf(chCheck) == -1) {
System.out.println("The Given Character is not present!");
return; // Exit early if the character is not found
}

StringBuilder sb = new StringBuilder(input);

int count = 1;
for (int i = 0; i < sb.length(); i++) {
if (sb.charAt(i) == chCheck) {
sb.setCharAt(i, (char) ('0' + count));
count++;
}
}


}
}

[umadevialamkonda]

public static String Replace_occurances(String s, char rc) {

StringBuilder ans= new StringBuilder();
int count=1;
if(s.indexOf(rc)==-1){
System.out.println("The given character "+rc+" is not present in the String");
}else{
for(int i=0;i<s.length();i++){
char ch=s.charAt(i);
if(ch==rc){
ans.append(count);
count++;
}else{
ans.append(ch);
}
}
}
return ans.toString();
}

[frustrated_majdoor]
