C code to remove spaces from a string | LeetCode
Write a C function to remove spaces from a string. The function header should be
void removeSpaces(char *str)
ie, “abc de” -> “abcde”

void removeSpace(char *str) {

  char *p1 = str, *p2 = str;

  do

    while (*p2 == ' ')

      p2++;

  while (*p1++ = *p2++);

}

void removeSpaces(char *str)

{

    // To keep track of non-space character count

    int count = 0;

    // Traverse the given string. If current character

    // is not space, then place it at index 'count++'

    for (int i = 0; str[i]; i++)

        if (str[i] != ' ') // maybe not write if count==i, just count++

            str[count++] = str[i]; // here count is

                                   // incremented

    str[count] = '\0';

}
