  • python
# Complete the alternatingCharacters function below.
def alternatingCharacters(s):
    pre = ''
    dele = 0
    for i in range(len(s)):
        if pre is not s[i]:
            pre = s[i]
        else:
            dele = dele + 1
        
    return dele
  • javascript
// Complete the alternatingCharacters function below.
function alternatingCharacters(s) {
    let pre = ''
    let del = 0
    for (let i = 0; i< s.length; i ++) {
        if ( pre != s[i]) {
            pre = s[i]
        } else {
            del += 1
        }
    }
    return del
