LeetCode - 942. 增减字符串匹配

奇怪了，同样的代码第一遍运行出错了…

/**
 * @param {string} S
 * @return {number[]}
 */
var diStringMatch = function(S) {
    let len = S.length;
    let ret = []
    let low = 0
    let a = S.split('')
    a.forEach(char => {
        if(char === 'I'){
            ret.push(low)
            low ++
        }else{
            ret.push(len)
            len --
        }
    })
    ret.push(a[a.length-1] === 'I' ? len : low)
    return ret
};
