Given an array of meeting time intervals consisting of start and end times [ [ s1, e1], [ s2, e2], …] ( si < ei ), determine if a person could attend all meetings.

**Example 1:
**
**Input: **[[0,20],[5,10],[20,30]]
**Output:** false
**Example 2:
**
**Input:** [[4,6],[7,10]
**Output: **true

def Meetings(intvals): intvals.sort() temp=0 for i in range(len(intvals)): if temp < intvals[i][0] : if intvals[i][0] > intvals[i][1] : return False else: temp=intvals[i][1] else: return False return True Time_inter = input('Time intervals : ') import ast #Abstract Syntax Tree Module Time_inter = ast.literal_eval(Time_inter) #Conversion of string to list print(Meetings(Time_inter))

**Input_1:**

Time intervals : [ [0,20], [5,10], [20,30] ]

**Output:**

False

**Input_2:**

Time intervals : [ [4,6], [7,10] ]

**Output:**

True

**Input_3:**

Time intervals : [ [1,2], [3,4], [6,10], [7,20] ]

**Output:**

False

**Input_4:**

Time intervals : [ [1,2], [3,4], [6,10], [11,20] ]

**Output:**

True
